[ Upstream commit dd363e2f7196278e7a30f509a0e8a841cb763b14 ]
The msm8939 has an additional higher operating point for the multi-media
peripherals. The higher throughput MM componets operate off of the
system-mm noc not the system noc.
system_mm_noc_bfdcd_clk_src is the source clock for the higher frequency
capable system noc mm.
Maximum frequency for the MM SNOC is 400 MHz.
Fixes: 1664014e4679 ("clk: qcom: gcc-msm8939: Add MSM8939 Generic Clock Controller")
