CB:46865 ("mb, soc/intel: Reorganize CNVi device entries in
devicetree") reorganized the devicetree entries to make the
representation of CNVi device consistent with other internal PCI
devices. Since a dummy generic device is added for the CNVi device,
`emit_sar_acpi_structures()` needs to first check if the device is PCI
before checking the vendor ID. This ensures that SAR table generation
is skipped only for PCIe devices with non-Intel vendor IDs and not for
the dummy generic device.

Individual drivers check whether the concerned device is enabled before

This change drops the PCI IDs for Jefferson Peak and Harrison Peak
CNVi modules from wifi/generic drivers as well as pci_ids.h. These IDs
actually represent the CNVi WiFi controller PCI IDs and are now
supported by intel/common/block/cnvi driver.
The only ID that is being dropped without adding support in
intel/common/block/cnvi driver is
PCI_DEVICE_ID_HrP_6SERIES_WIFI(0x2720) since this was not found in the
list of PCI IDs for any SoC.

This change reorganizes drivers/wifi/generic to add a new
device_operations structure for dummy CNVi device. This is done to
make the organization of CNVi PCI device in devicetree consistent
with all the other internal PCI devices of the SoC i.e. without a chip
around the PCI device.
Thus, with this change, CNVi entry in devicetree can be changed from:
```
chip drivers/wifi/generic
register "wake" = "xxyyzz"
device pci xx.y on end # CNVi PCI device
end
```
to:
```
device pci xx.y on
chip drivers/wifi/generic
register "wake" = "xxyyzz"
device generic 0 on end # Dummy CNVi device
end
end # CNVi PCI device
```
The helper functions for ACPI/SMBIOS generation are also accordingly
updated to include _pcie_ and _cnvi_ in the function name.

This change splits `wifi_generic_fill_ssdt()` into following two
functions:
1. `wifi_ssdt_write_device()`: This function writes the device, its
address, _UID and _DDN.
2. `wifi_ssdt_write_properties()`: This function writes the properties
for WiFi device like _PRW, regulatory domain and SAR.
This split is done so that the device write can be skipped for
CNVi devices in follow-up CLs. It will allow the SoC controller
representation for CNVi PCI device to be consistent with other
internal PCI devices in the device tree i.e. not requiring a
chip driver for the PCI device.
Because of this change, _PRW and SAR will be seen in a separate
block in SSDT disassembly, but it does not result in any functional
change.
Observed difference:
Before:
Scope (\_SB.PCI0.PBR1)
{
Device (WF00)
{
Name (_UID, 0xAA6343DC)
Name (_DDN, "WIFI Device")
Name (_ADR, 0x0000000000000000)
Name (_PRW, Package() { 0x08, 0x03 })
}
}
After:
Device (\_SB.PCI0.PBR1.WF00)
{
Name (_UID, 0xAA6343DC)
Name (_DDN, "WIFI Device")
Name (_ADR, 0x0000000000000000)

This change limits the scope of `wifi_generic_fill_ssdt()` and
`wifi_generic_acpi_name()` to generic.c since they are not used
outside of this file anymore. Also, since there is no need to split
SSDT generator into two separate functions,
`wifi_generic_fill_ssdt_generator()` is dropped and `.acpi_fill_ssdt`
directly points to `wifi_generic_fill_ssdt()`.

Currently, drivers/intel/wifi is a PCI driver (provides `struct
pci_driver`) as well as a chip driver (provides `struct
chip_operations`). However, there is no need for a separate chip
driver for the WiFi device since drivers/wifi/generic already provides
one.
Having two separate chip drivers makes it difficult to multi-source
WiFi devices and share the same firmware target without having to add
a probe property for each of these devices. This is unnecessary since
the WiFi driver in coreboot is primarily responsible for:
1. PCI resource allocation
2. ACPI SSDT node generation to expose wake property and SAR tables
3. SMBIOS table generation
For the most part, coreboot can perform the above operations without
really caring about the specifics of which WiFi device is being used
by the mainboard. Thus, this change drops the driver for intel/wifi
and moves the PCI driver support required for Intel WiFi chips into
drivers/wifi/generic. The PCI driver is retained for backward
compatibility with boards that never utilized the chip driver to
support Intel WiFi device. For these devices, the PCI driver helps
perform the same operations as above (except exposing the wake
property) by utilizing the same `wifi_generic_ops`.
This change also moves DRIVERS_INTEL_WIFI config to
wifi/generic/Kconfig.

This change drops the dependency of DRIVERS_WIFI_GENERIC on
HAVE_ACPI_TABLES as the driver provides operations other than the ACPI
support for WiFi devices. Since the dependency is now dropped, ACPI
operations in generic.c are guarded by CONFIG(HAVE_ACPI_TABLES).

This change drops maxsleep parameter from chip config and instead
hardcodes the deepest sleep state from which the WiFi device can wake
the system up from to SLP_TYP_S3. This is similar to how other device
drivers in coreboot report _PRW property in ACPI. It relieves the
users from adding another register attribute to devicetree since all
mainboards configure the same value. If this changes in the future, it
should be easy to bring the maxsleep config parameter back.
