drivers/vpd: Add VPD region to default FMAP when selected

Browse Source 
Currently, use of the VPD driver to read VPD tables from flash
requires the use of a custom FMAP with one or more VPD regions.
Extend this funtionality to boards using the default FMAP by
creating a dedicated VPD region when the driver is selected.

Test: build qemu target with CONFIG_VPD selected, verify entry
added to build/fmap.fmd.
