clk: tegra: Add support for the Tegra132 CAR IP block

Tegra132 CAR supports almost the same clocks as Tegra124 CAR. This
patch mostly deals with the small differences.

Since Tegra132 contains many of the same PLL clock sources used on
Tegra114 and Tegra124, enable them in drivers/clk/tegra/clk-pll.c when
the kernel is configured to include Tegra132 support.

This patch is based on several patches from others:

1. a  patch from Peter De Schrijver:

http://lkml.iu.edu/hypermail/linux/kernel/1407.1/06094.html



2. a patch from Bill Huang ("clk: tegra: enable cclk_g at boot on
Tegra132"), and

3. a patch from Allen Martin ("clk: Enable tegra clock driver for
tegra132").
