Many of the Tegra DT binding documents say nothing about the clocks or
clock-names properties, yet those are present and required in DT files.
This patch simply updates the documentation file to match the implicit
definition of the binding, based on real-world DT content.
All Tegra bindings that mention clocks are updated to have consistent
wording and formatting of the clock-related properties.

The PWM client cells format is documented in the generic pwm.txt
documentation and duplicated in all PWM driver bindings. Remove
duplicate information and reference pwm.txt instead.

The second cell in the PWM specifier denotes the period in nanoseconds,
not the duty cycle. The latter can be freely configured at runtime and
a PWM with a fixed duty cycle would be rather pointless.

Add auxdata to instantiate the PWFM controller from a device tree,
include the corresponding nodes in the dtsi files for Tegra 20 and
Tegra 30 and add binding documentation.
