mmc: mtk-sd: implement waiting for DAT0 line state
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.
