From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>

[ 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.
