sb,soc/intel: Add wake source fields in GNVS
For the moment, these are most not used but become a necessity
for a unified <soc/nvs.h> approach.
They would be required for the implementation of _SWS method
for OSPM to determine the reason for system waking up. The related
hardware registers are present with these platforms.
It's expected that ACPI power-management related GNVS entries are
grouped together to form a single struct in later works.
