Re: [PATCH RESEND 8/8] mmc: omap4: hsmmc: fix module re-insertion

From: Balaji T K <redacted>

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.
