clk: tegra: Update binding doc for Tegra132 



Tegra132 has almost the same clock structure than Tegra124. This patch
documents the missing clock IDs.

[paul@pwsan.com: updated binding documentation to reflect the recent
 split of Tegra124 clock IDs into a Tegra124/132-common file and a
 Tegra124-specific file]
