ACPI: Select ACPI_SOC_NVS only where suitable

Having some symmetry with <soc/nvs.h> now allows to reduce
the amount of gluelogic to determine the size and cbmc field
of struct global_nvs.

Since GNVS creation is now controlled by ACPI_SOC_NVS,
drivers/amd/agesa/nvs.c becomes obsolete and soc/amd/cezanne
cannot have this selected until <soc/nvs.h> exists.
