mmc: tmio: use -EPROBE_DEFER if driver can't find regulator
Current tmio driver tries to use default ocr_avail if 1) it couldn't
find regulator and 2) if platform data doesn't have ocr_mask.
But, there is no guarantee that regulator driver probe is faster than
TMIO driver probe. TMIO driver will not use regulator in such case.
By this patch, TMIO driver returns -EPROBE_DEFER if it couldn't find
regulator and if platform doesn't have ocr_mask. Because, there is a
possibility that regulator has not been probed, but the user expects it.
This patch changes tmio_mmc_host_probe() behavior, but there is no user
who has conflict.
