soc/intel/alderlake: Add GPIO definition for CPU PCIe vGPIO

Adding GPIO definition for community 3 which is CPU reserved GPIO used
by CPU side PCIe root ports. We did not have this definition since
FSP used to program this GPIOs. Now, instead of FSP, coreboot programs
CPU PCIe GPIOs for CLKSRC and lanes to put GPIOs in native mode.
Thus adding definition of this virtual GPIOs in this CL.

BUG=None
BRANCH=None
TEST=Check if correct registers are being programmed
