ACPI: Drop redundant CBMEM_ID_ACPI_GNVS allocations

Browse Source 
Allocation now happens prior to device enumeration. The
step cbmem_add() is a no-op here, if reached for some
boards. The memset() here is also redundant and becomes
harmful with followup works, as it would wipe out the
CBMEM console and ChromeOS related fields without them
being set again.
