Add clock support for i.MX8MQ. Most of the clocks can be configured

using a single register which consists of root, div, pre-div, clock
gate and src (mux).  The device tree node references the root clock,
and an "enable" call has to enable the clock's parents so that the
clock gate is toggled as well.
