ACPI: Refactor ChromeOS specific ACPI GNVS

The layout of GNVS has expectation for a fixed size
array for chromeos_acpi_t. This allows us to reduce
the exposure of <chromeos/gnvs.h>.

If chromeos_acpi_t was the last entry in struct global_nvs
padding at the end is also removed.

If device_nvs_t exists, place a properly sized reserve for
chromeos_acpi_t in the middle.

Allocation from cbmem is adjusted such that it matches exactly
the OperationRegion size defined inside the ASL.
