drivers/wifi/generic: Split wifi_generic_fill_ssdt into two functions
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)
}
Scope (\_SB.PCI0.PBR1.WF00)
{
Name (_PRW, Package() { 0x08, 0x03 })
}
