ARM: OMAP4: Reduce the static IO mapping

EMIF, GMPC and DMM driver can ioremap() the address space as part of driver intialisation and there is no need to have static IO mapping for them. Hence remove the un-used static IP space and let the respective drivers manage it as part if driver init. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
