There are two dividers used to derive bus clock from system clock:
system clock is divided by SCKDIV+1, then by BCKDIV+1. SCKDIV divider
has been ignored up to now, which is no problem as long as it is 0.
Take SCKDIV into account for bus clock calculation.

The calculation of the best divider value for a requested clock rate
always returned a value that was slightly too large. It was also not
protected against possible divisions by zero.
Request for very low, but non zero rates would cause the ACLK divisor
field to overflow. Catch this situation by using the maximum value.
The internal function aclk_set_rate() calculates the correct divider
value, but doesn't write it back to the register. Add the write back.

The evaluation board is driven with 1.2V core voltage, so system clock
must not exceed 192 MHz, bus clock must not exceed 110 MHz. Choose
appropriate values and set DTCMWAIT accordingly. Adapt UART setting to
avoid console log interruption and wait for the specified locking time
of 300us to pass.

This fixes a bug introduced by 807e8e4067 ("mmc: Fix sd/sdio/mmc
initialization frequency retries") that prevented SDIO drivers from
performing SDIO commands in their probe routines -- the above patch
called mmc_claim_host() before sdio_add_func(), which causes a deadlock
if an external SDIO driver calls sdio_claim_host().
Fix tested on an OLPC XO-1.75 with libertas on SDIO.

The per-vm mutex doesn't prevent this completely, a flush coming from the

VM. Not to mention that if/when we get per-client/channel VM, this will
