mmc: tmio: remove useless TMIO_MASK_CMD handling in tmio_mmc_host_probe()
TMIO_MASK_CMD is properly enabled in tmio_mmc_start_command().
We have no reason to set it up in tmio_mmc_host_probe(). (If we
really wanted to set it in the probe, we would have to do likewise
when resuming.)
Even worse, the following code is extremely confusing:
_host->sdcard_irq_mask &= ~irq_mask;
The logic is opposite between "->sdcard_irq_mask" and "irq_mask".
The intention is not clear at a glance.
