soc/intel/meteorlake: Account for GSPI2 everywhere

Commit e54a8fd43247d767f16a37f3e3150b2915d809bc (soc/intel/meteorlake:
Add entry for GSPI2 device) added an entry for the GSPI2 device in the
devicetree, but did not add any other entries. Ensure that the rest of
the code is aware of the GSPI2 device to avoid any problems.
