clk: qcom: gcc-msm8939: Add MSM8939 Generic Clock Controller

This patch adds support for the MSM8939 GCC. The MSM8939 is based on the
MSM8916. MSM8939 is compatible in several ways with MSM8916 but, has
additional functional blocks added which require additional PLL sources. In
some cases functional blocks from the MSM8916 have different clock sources
or different supported frequencies.
