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.

The pwm node still seems to be in the wrong place. Sorting by reg value,
it should be after i2c at 20205000 and before sdhci at 7e300000, as I
mentioned before.

I'm really sorry. I've used the wrong source. I make v4.
