clk: tegra: Update binding doc for Tegra132

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

[[e-mail]: updated binding documentation to reflect the recent
split of Tegra124 clock IDs into a Tegra124/132-common file and a
Tegra124-specific file]

 This binding uses the common clock binding:
 Documentation/devicetree/bindings/clock/clock-bindings.txt
···
 for muxing and gating Tegra's clocks, and setting their rates.
 
 Required properties :
-- compatible : Should be "nvidia,tegra124-car"
+- compatible : Should be "nvidia,tegra124-car" or "nvidia,tegra132-car"
 - reg : Should contain CAR registers location and length
 - clocks : Should contain phandle and clock specifiers for two clocks:
   the 32 KHz "32k_in", and the board-specific oscillator "osc".
 - #clock-cells : Should be 1.
   In clock consumers, this cell represents the clock ID exposed by the
-  CAR. The assignments may be found in header file
-  <dt-bindings/clock/tegra124-car.h>.
+  CAR. The assignments may be found in the header files
+  <dt-bindings/clock/tegra124-car-common.h> (which covers IDs common
+  to Tegra124 and Tegra132) and <dt-bindings/clock/tegra124-car.h>
+  (for Tegra124-specific clocks).
 - #reset-cells : Should be 1.
   In clock consumers, this cell represents the bit number in the CAR's
   array of CLK_RST_CONTROLLER_RST_DEVICES_* registers.
