[PATCH] sdhci: add ops to force delay in operations due to silicon issues

PXA168 controller needs at least 8 clocks before it can start the
next transaction.  When the bus speed is slow the CPU can get back
to the controller before the 8 clocks causing SD CRC errors.

Add a new host->op to call into platform specific code to delay
the operation until the time has expired
