soc/inte/*/gpio; Add GPE_EN and GPE_STS register definition
coreboot needs to set GPE_EN bit for the GPIOs which are wake capable
from s0ix/sleep. Due to GPIO locking mechanism, coreboot/OS will not
be able to write GPE_EN register post GPIO has been locked.
This patch adds support in SoC code to provide correct offset for
GPE_EN and GPE_STS registers to the common code.
Plan is to use this offsets to set GPE_EN bits before GPIO locking
in coreboot which will be part of subsequent CL.
BUG=b:222375516
BRANCH=firmware-brya-14505.B
TEST=Check if code compiles for Brya and correct offset values are printed.
