[MTD] LPDDR extended physmap driver to support LPDDR flash
Physmap is a generic map driver for different platforms and flash types.
We added support of LPDDR to physmap.
All changes here are related to introduction of new pfow_base parameter.
This parameter is valid in case of LPDDR chips only.

This provides a 'mapping' driver which allows the NOR Flash and
ROM driver code to communicate with chips which are mapped
