soc/amd/stoneyridge: correct GPIO emission error in ACPI

It can not emit byte data without BytePrefix.

design to:
Or (Local5, GPIO_PIN_OUT, Local5)

error due to GPIO_PIN_OUT is 0x40 but 0x40 encoding means
nothing in AML spec.
so it will include next emitted string in Or:
Or (Local5, Local5, \_SB.GPW2)

fix:
Store (0x40, Local0)
Or (Local5, Local0, Local5)

BUG=b:110962003

BRANCH=master
TEST=emerge-grunt coreboot
     extract SSDT then check ACPI syntax is correct
