[PATCH] mmc: mmc_spi: fix timeout calculation

[Tobias Schramm]

Previously the cycle timeout was converted to a microsecond value but
then incorrectly treated as a nanosecond timeout. This patch changes
the code to convert both the nanosecond timeout and the cycle timeout
to a microsecond value and use that directly.
