baytrail: Add padding to the end of device_nvs to match ACPI
ACPI globalnvs.asl expects the gnvs memory area size to be 0x2000. Padding has been added to device_nvs struct to reserve the full 0x2000 bytes for gnvs usage. No known issues are caused by having the GNVS area shorter than what ACPI thinks. Since there's nothing defined in this area, O/S shouldn't try to access it. Only problem might be if O/S notices the SSDT is located within the GNVS defined area. I verified that the next table written to memory (SSDT) is 0x2000 past GNVS start using a custom-designed Baytrail-I motherboard based on the Intel Bayley Bay CRB.
