soc/amd/stoneyridge: use common AMD CPU power state ACPI generation
Instead of using the PSTATE SSDT generated by binaryPI, use the common AMD code by selecting SOC_AMD_COMMON_BLOCK_ACPI_CPU_POWER_STATE. To match the SSDT from binaryPI, set ACPI_SSDT_PSD_INDEPENDENT to n. There are two differences to the binaryPI SSDT: Now coreboot includes the C1 state in the _CST package instead of just having the kernel add this due to the ACPI_FADT_C1_SUPPORTED bit being set and the address of the PS_STS_REG P state status MSR is written to the corresponding field of the _PCT package instead of being 0. TEST=On Careena the new P and C state ACPI packages are nearly identical to the ones from the SSDT from binaryPI with the two functional differences mentioned above.
