Simon Glass 542b5f8567 tegra: mmc: Set the bus width correctly 
The driver currently does not reset bit 5 of the hostctl register even if
the MMC stack requests it. Then means that once a bus width of 8 is
selected it is not possible to change it back to 1. This breaks
'mmc rescan' which needs to start off with a bus width of 1.

The problem was surfaced by enabling CONFIG_DM_MMC_OPS on tegra. Without
this option the MMC stack fully reinits the driver on a 'mmc rescan'.
But with this option driver model does not re-probe a driver once it has
been probed once.

Fix the driver to honour the request.
