Wolfram Sang 67b5870a35 mmc: tmio: avoid glitches when resetting 
[ Upstream commit 2e586f8a5b ]

If we reset because of an error, we need to preserve values for the
clock frequency. Otherwise, glitches may be seen on the bus.

To achieve that, we introduce a 'preserve' parameter to the reset
function and the IP core specific reset callbacks to handle everything
accordingly.
