[PATCH v2 1/3] mmc: Convert hs400_tuning flag from u8 to bool

[Marek Vasut]

This hs400_tuning is a flag, make it bool. No functional change.
This will be useful in the following patch, which adds another
more generic flag, where the compiler can better use the space
now reserved for the u8 to store more flags in it.
