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.
