ARM: tegra30: create a DT header defining CLK IDs

Create a header file to define the clock IDs used by the Tegra30 clock
binding. Remove the list of definitions from the binding documentation,
and refer the reader to the header file.

This will allow the same header to be used by both device tree files,
and drivers implementing this binding, which guarantees that the two
stay in sync. This also makes device trees more readable by using names
instead of magic numbers.

 - 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 first 130 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
-  registers. These IDs often match those in the CAR's RST_DEVICES registers,
-  but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In

-  explicitly handle these special cases.
-
-  The balance of the clocks controlled by the CAR are assigned IDs of 160 and
