With the recent changes on mmc driver, we saw that the boot is ~5 secs longer compared to v2021.07 on mediatek platforms.
This regression is seen during mmc_init and caused by the following patch [1].
Indeed since we did not support poll dat0, we fulfilled the condition of [1] and a delay of 500 ms was added for every __mmc_switch call.
By adding the support of wait_dat0(), we now don't need to mdelay during mmc_init anymore.
