[PATCH] clk: tegra114: Initialize host1x and related clocks

[Thierry Reding]

From: Mikko Perttunen <mperttunen-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

The host1x clock should be a child of PLLC and runs too fast by default,
so throttle it while at it. The disp1 and disp2 clocks should use PLLP
by default. They will usually be reparented to either pll_d_out0 or
pll_d2_out0 as part of the display driver setup.
