mmc: omap_hsmmc: fix module re-insertion
OMAP4 and OMAP3 HSMMC IP registers differ by 0x100 offset.
Adding the offset to platform_device resource structure
increments the start address for every insmod operation.
MMC command fails on re-insertion as module due to incorrect register
base. Fix this by updating the ioremap base address only.
