mmc: tmio: add new TMIO_MMC_HAVE_HIGH_REG flags
The accessibility checking method to the higher register was added by
69d1fe18e92afb (mmc: tmio: only access registers above 0xff, if available)
But, it doesn't care 32bit register. It is impossible to calculate it
from the resource size, since there is 16/32 bit register IP (e.g. VERSION
is located on 0xe2 if 16bit register, but it is located on 0x1c4 if 32bit
register).
This patch adds new TMIO_MMC_HAVE_HIGH_REG flags, tmio_mmc driver has it,
and sh_mobile_sdhi doesn't have it today.
