Subject: [PATCH] UBUNTU - ARM: Initializing gpmc before accessing flash

Adding initialization of the General Purpose Memory Controller
(gpmc) in 'omap3beagle_flash_init'.

After Lucid gpmc init was decoupled from nand flash init and
got its own init function.  This change was not reflected in
'omap3beagle_flash_init' resulting in a lookup failure when
probing for flash.
