Subject: [PATCH] davinci: dm365: disable pulldowns for all MMC/SD1 pins.

This patch disables internal pulldowns for all MMC/SD1
pins. Presently only MMCSD1_CMD pin's pull down is
disabled, but with this some MMC/SD cards do not get
detected on MMC/SD1 slot of the EVM.

The problem was reproducible with SanDisk 4GB SDHC card.
