omap: RX51: Remux to pull eMMC lines down when powering off
It has been discovered that, when eMMC is powered off, current
will flow from OMAP eMMC data pull-ups to the eMMC voltage supply.
Configuring pads for OMAP off-mode does not help because eMMC is
powered off independently of OMAP off-mode. Hence the pads are
now re-configured when eMMC is powered on or off.
