This is preliminary and not fully tested patch which adds
support for the global clock controller found on the MSM8916
based devices. It allows the various device drivers to probe
and control their clocks and resets.

This should be 0x4d044. The one above corresponds to the byte0_cbcr register.

This should be 0x4d000. Same reason as above.

mdss clocks look fine otherwise.
