ARM: 6244/1: mmci: add variant data and default MCICLOCK support
Add a variant_data structure to handle the differences between the
various variants of this peripheral. Add a first quirk for a default
MCICLOCK value, required on the Ux500 variant where the enable bit needs
to be always set, since it controls access to some registers.
