[U-Boot] [PATCH 1/2] mmc: Fix timeout values passed to mmc_wait_dat0()

[Peng Fan]

> Subject: [PATCH 1/2] mmc: Fix timeout values passed to mmc_wait_dat0()
> 
> 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().
> 
> Fixes: bb98b8c5c06a ("mmc: During a switch, poll on dat0 if available and
> check the final status")
