[PATCH v4] ARM: dts: add bcm2835-pwm bindings

[Bart Tanghe]

To probe the bcm2835-pwm driver properly, this dts bindings has to be added 
to the bcm2835 dtsi file.
In expectation of a bcm2835 clock driver, I've added fixed-clock clock binding.

Changes in v4:
 - node added by reg value

Applied, thanks.
