[PATCH] ARM: tegra: move serial clock-frequency attr into the Tegra30 dtsi

[Stephen Warren]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

No Tegra30 Platform is running PLL_P at another rate than 408MHz, nor is
any using any other PLL as UART source clock. Move attribute into SoC
level dtsi file to slim down board DT files.

I have applied this to Tegra's for-3.9/dt branch.
