[PATCH] mmc: omap4: hsmmc: fix module re-insertion

[Balaji T K <balajitk@ti.com>]

OMAP4 and OMAP3 HSMMC IP registers differ by 0x100 offset.
Addng 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.
