mmc: tmio: check ILL_FUNC instead of CBSY
Some controllers need to check SD bus status when writing data.
Then, it checks ILL_FUNC bit on SD_INFO2 register,
and this method is controlled via TMIO_MMC_HAS_IDLE_WAIT flags.
Same method is required on tmio_mmc_data_irq() which will
be called after writing data.
Current driver is checking CBSY bit for this purpose,
but, some controllers doesn't have CBSY bit.
This patch checks ILL_FUNC bit instead of CBSY bit
if it has TMIO_MMC_HAS_IDLE_WAIT flags
