[PATCH 2/5] ARM: tegra: reparent sclk to pll_c_out1

From: Stephen Warren <swarren at nvidia.com>

pll_p_out4 needs to be used for other purposes. Reparent sclk so that
it runs from pll_c. Change sclk's rate to 120MHz from 108MHz since this
is the lowest precise rate that can be achieved by dividing the pll_c
rate without reducing the sclk rate. (600/5=120, 600/5.5=109.0909...,
600/6=100).
