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".
