clk: qcom: Add driver for MSM8909 GCC

Browse Source 
The Global Clock Controller (GCC) in the MSM8909 SoC provides clocks,
resets and power domains for the various hardware blocks in the SoC.
Add a driver for it to make it possible to enable additional
functionality for the SoC.

Work on this driver was originally started independently by Dominik,
I picked it up and added missing clocks/resets, as well as various
cleanup to bring it into shape for mainline.
