drivers/vpd: Add VPD support
VPD reference: https://chromium.googlesource.com/chromiumos/platform/vpd/+/master/README.md
Copy ChromeOS VPD driver to add support for VPD without CROMEOS.
Possible use case:
* Storing calibration data
* Storing MAC address
* Storing serial
* Storing boot options
+ Now it's possible to define the VPD space by choosing
one of the following enums: VPD_ANY, VPD_RW, VPD_RO.
+ CHROMEOS selects now VPD as part of it.
+ VPD is implemented as driver.
