intel/apollolake: Add CBMEM console to GNVS
CBMEM console stores all the console logs in CBMEM. Address of this
location in CBMEM where console logs are stored needs to be passed up to
OS using GNVS.
1. Add CBMC to GNVS fields in globalnvs.asl
2. Add cbmc member to global_nvs_t structure in nvs.h
3. Initialize gnvs->cbmc to address of cbmem console
