nb/amd/pi/00730F01: request binaryPI to use \_SB_ scope in PSTATE SSDT
Instead of having binaryPI generate a PSTATE SSDT that uses \_PR_ as the scope for the CPU objects and patching this SSDT in coreboot to use the \_SB_ scope in patch_ssdt_processor_scope, request binaryPI to use the \_SB_ scope instead by setting the late platform configuration option ProcessorScopeInSb to true. TEST=APU2 still boots and Linux doesn't show any ACPI errors with this patch applied and it prints "ACPI: \_SB_.P000: Found 2 idle states".
