Sorry, my statements were not clear, I meant once driver is
acceptable & still living in mach-omap2, platform code dealing
with peripherals on gpmc would be adapted to make use of gpmc
driver. Moving driver to new location is only planned as a
separate commit after, before mentioned changes. Hope with this
clarification we are on same track.

Greg suggested to send gpmc driver to new memory folder.

In the next version, gpmc driver would still be in mach-omap2,
moving to new location can be done later.
