Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Matt DeVillier, Martin Roth, Fred Reitberger,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

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.
