Add a new sdhci quirk, SDHCI_QUIRK_WAITFOR_RESET_ASSERTED, to work around
TI OMAP controllers which will return the reset-in-progress bit as zero if
you read the status register too fast after setting the reset bit.

The zero is apparently from a stale snapshot of the internal state presented
in the interface register, and leads to a false indication that the reset
is complete when it either hasn't started yet or is in-progress.  The
workaround is to first loop until the bit is seen as asserted, then do the
normal loop waiting to see it de-asserted.
