mmc_wait_dat0() expects timeout argument to be in usec units. But some overlying functions operate on timeout in msec units. Convert timeout from msec to usec when passing it to mmc_wait_dat0().
This fixes 'avb' commands on BeagleBoard X15, because next chain was failing:
get_partition() -> mmc_switch_part() -> __mmc_switch() -> mmc_wait_dat0()
when passing incorrect timeout from __mmc_switch() to mmc_wait_dat0().
