lynxpoint: Move ACPI NVS into separate CBMEM table

Browse Source 
The ACPI NVS region was setup in place and there was a CBMEM
table that pointed to it.  In order to be able to use NVS
earlier the CBMEM region is allocated for NVS itself during
the LPC device init and the ACPI tables point to it in CBMEM.

The current cbmem region is renamed to ACPI_GNVS_PTR to
indicate that it is really a pointer to the GNVS and does
not actually contain the GNVS.
