All of our MMC clocks are of the MP clock type. A few MMC clocks on some
SoCs, such as MMC2 on the A83T, support new/old timing mode switching.
>From a clock rate point of view, when the new timing mode is active. the
output clock rate is halved.
This patch adds a special wrapper class of clocks, MP_MMC, around the
generic MP type clocks. The rate related callbacks in ccu_mp_mmc_ops
for this class look at the timing mode bit and apply the /2 post-divider
when needed, before passing it through to the generic class ops,
ccu_mp_ops.

consistent with the mux structure name

Introduce support for the clocks that combine a linear divider and a
power-of-two based one.
