platform: arm64: thinkpad-t14s-ec: add system PM hooks
Improve support for system suspend. The register information has been
extracted from the ACPI DSDT code handling Windows Modern Standby. I
took over the weird multi-write function from the ACPI DSDT code where
it is called ECWS.
In addition to writing to the 0xE0 register, the ACPI Windows Modern
Standby code also does some changes to the thermal configuration. This
part is not implemented.
After this patch the laptop's power and LID LEDs will switch into the
typical breathing animation when the system is suspended and enabled
normally again after resuming.
