clk: qcom: Add global clock controller driver for MSM8917

Browse Source 
This driver provides clocks, resets and power domains needed for various
components of the MSM8917 SoC and the very similar QM215 SoC.

According to [1] in the downstream kernel, the GPU clock has a different
source mapping on QM215 (gcc_gfx3d_map vs gcc_gfx3d_map_qm215).
