[PATCH 1/2] ARM: dts: msm: Add clock controller nodes and hook into uart

[Stephen Boyd]

Add the necessary DT nodes to probe the clock controllers on MSM
devices as well as hook up the uart nodes to the clock
controllers. This should allow us to boot to a serial console on
all DT enabled MSM platforms.
