Add a driver for the A53 Clock Controller. It is a hardware block that
implements a combined mux and half integer divider functionality. It can
choose between a fixed-rate clock or the dedicated A53 PLL. The source
and the divider can be set both at the same time.
This is required for enabling CPU frequency scaling on platforms like
MSM8916.

+Qualcomm A53 CPU Clock Controller Binding
+------------------------------------------------
+The A53 CPU Clock Controller is hardware, which provides a combined
+mux and divider functionality for the CPU clocks. It can choose between
+a fixed rate clock and the dedicated A53 PLL. This hardware block is used
+on platforms such as msm8916.

Same comment on the ordering. With that, for the binding:

Thanks for reviewing, Rob. I am also going to make this a child node
as discussed here [1]. Please let me know if you have any comments.
