mmc: sdhci: fix mmc busy timeout handling

With eMMC there is a good chance, that the mmc device remains busy for
extended periods of time after certain operations.
The current approach to handle this was to increase the timeout for
all commands up to a maximum.

Rather than this, do an extended wait for !busy in the relevant case
only, not affecting the general mmc cmd busy timeout.
