After ChromeOS NVS was moved to a separate allocation and the use
of multiple OperationRegions, maintaining the fixed offsets is not
necessary.
Use actual structure size for OperationRegions, but align the
allocations to 8 bytes or sizeof(uint64_t).

This adds full EINJ support with trigger action tables. The actual
error injection functionality is HW specific. Therefore, HW specific
code should call acpi_create_einj with an address where action table
resides. The default params of the action table are filled out by the
common code. Control is then returned back to the caller to modify or
override default parameters. If no changes are needed, caller can
simply add the acpi table. At runtime, FW is responsible for filling
out the action table with the proper entries. The action table memory
is shared between FW and OS. This memory should be marked as reserved
in E820 table.
Tested on Deltalake mainboard. Boot to OS, load the EINJ driver (
modprobe EINJ) and verify EINJ memory entries are in /proc/iomem.
Further tested by injecting errors via the APEI file nodes. More
information on error injection can be referenced in the latest ACPI
spec.

Remove typedef device_nvs_t and move struct device_nvs
outside of global_nvs. Also remove padding and the reserve
for chromeos_acpi_t.

Add support for the Intel LPIT table to support reading Low Power Idle
Residency counters by the OS. On platforms supporting S0ix sleep states
there can be two types of residencies:
* CPU package PC10 residency counter (read from MSR via FFH interface)
* PCH SLP_S0 assertion residency counter (read via memory mapped
interface)
With presence of one or both of these counters in the LPIT table, Linux
dynamically adds the corresponding attributes to the cpuidle sysfs
interface, that can be used to read the residency timers:
* /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
* /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
The code in src/acpi implements generic LPIT support. Each SoC or
platform has to implement `acpi_fill_lpit` to fill the table with
platform-specific LPI state entries. This is done in this change for
soc/intel/common, while being added as its own compilation unit, so SoCs
not yet using common acpi code (like Skylake) can use it, too.
Reference:
https://uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf
Test: Linux adds the cpuidle sysfs interface; Windows with s0ix_enable=1
boots without crashing with an INTERNAL_POWER_ERROR.
- Windows and Linux tested on google/akemi together with CB:49046
- Linux tested on clevo/cml-u, supermicro/x11ssmf together with CB:49046

Allocation now happens prior to device enumeration. The
step cbmem_add() is a no-op here, if reached for some
boards. The memset() here is also redundant and becomes
harmful with followup works, as it would wipe out the
CBMEM console and ChromeOS related fields without them
being set again.

ACPI_SATA_GENERATOR is currently used to include sata.c in
ramstage. However, there is no need to guard this inclusion using a
separate Kconfig. All other files that deal with ACPI tables are
included based on the state of HAVE_ACPI_TABLES. This change includes
sata.c in ramstage if HAVE_ACPI_TABLES is selected. If the ACPI
function isn't used, linker will optimize it out.

While I was working on updating the headers to move copyrights into
the AUTHORS file, I got a request to switch to SPDX headers as well.
Linux has moved completely to SPDX headers, which are easier to
maintain, have good definitions, are very short, and can be checked
automatically. This is completely unlike our current header situation.

In the ACPI specification the PM1 register locations are well
defined, but the sleep type values are hardware specific. That
said, the Intel chipsets have been consistent with the values
they use. Therefore, provide those hardware definitions as well
a helper function for translating the hardware values to the
more high level ACPI sleep values.
