mmc: Fix potential timer value truncation
On 64bit systems the timer value might be truncated to a 32bit value
causing malfunctions. For example on ARM the timer might start from 0
again only after a cold reset. The 32bit overflow occurs after a bit
more than 49 days (1000 Hz counter) so booting after that time may lead
to a surprise because the board might become stuck requiring a cold
reset.
