From: Stephen Boyd <sboyd@xxxxxxxxxxxxxx>
Every board file calls msm_clock_init() to initialize the clocks
and msm_clock_init() in turn calls msm_clk_soc_init() to do any
SoC specific initialization. Invert the call order so that boards
that require SoC specific initialization call the SoC specific
function first which then calls the generic msm_clock_init().
This removes one more obstacle in the path of multi-arch kernels
in mach-msm.
