From: Balaji T K <balajitk@xxxxxx> 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.
