soc/amd/stoneyridge: 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=Careena still boots and Linux doesn't show any ACPI errors with
this patch applied. With only patch_ssdt_processor_scope removed, but
the ProcessorScopeInSb option not set, Linux will complain that it can't
resolve the \PR.P00x symbols.
