mmc: omap4: hsmmc: Fix improper card detection while booting
While booting OMAP4 ES2.0 boards, cards on MMC1 and MMC2 controllers are not getting detected sometimes. During reset of command/data line, wrong pointer to base address was passed while read operation to SYSCTL register, thus impacting the updated reset logic. Passing the correct base address fixes the issue.
