soc/amd/{cezanne,common}/acpi: Add _OSC method
The linux kernel requires a valid _OSC method. Otherwise the _LPI table
is ignored.
See https://source.chromium.org/chromiumos/chromiumos/codesearch/+/main:src/third_party/kernel/v5.10/drivers/acpi/bus.c;l=324
Before this patch:
acpi_processor_get_lpi_info: LPI is not supported
After this patch:
acpi_processor_evaluate_lpi: ACPI: \_SB_.CP00: ACPI: Found 4 power states
BUG=b:178728116
TEST=Boot OS and verify _LPI table is parsed
