Subject: [PATCH] UBUNTU - ARM: Using gpmc function to init nand flash.

The General Purpose Memory Controller (gpmc) initialization was
decoupled from flash init but the changes were not reflected
in omap3beagle_flash_init.

This is the board specific portion of patch:
f450d86790ebf72ac93c7ea5addd6fa278aae64c

This patch is supposed to be part of 2.6.36 but only a subset is
used to avoid dealing with the substantial amount of gpmc changes
that will go in.  These changes should be brought in when we
rebase to 2.6.36.
