sb,soc/amd: Move _PIC method to global scope
Fix regression with commit aa969e887a ACPI: Move PICM declaration.
While mentioned in the commit message there already, the default
value for AMD boards changed from IOAPIC mode to PIC mode.
ACPI 6.3 spec has this text regarding _PIC method:
If the platform CPU architecture supports PIC mode and the method
is never called, the platform runtime firmware must assume PIC mode.
If MADT has IOAPIC entries, OS will want to change to APIC model. But
the method _PIC was not in the global scope so it could not be called
and therefore _PRT continued to report PIC model interrupt routing.
Already fixed for soc/amd/picasso in commit 839f668.
