With the upcomming PWM clock patch (see https://lkml.org/lkml/2015/12/6/74)
PWM can now be used and can be added in the RPI devicetree.

Looks good to me.  I'll try to keep a watch on the clock tree and
include this (possibly moved to bcm283x.dtsi depending on if 2836 lands
first) when I have something I can pull from for the BCM2835_CLOCK_PWM
definition.

Did the rebase and merged to bcm2835-dt-next.
