Very much Ack on the new subsystem. It uses the interface declarations
as the previously separate pwm drivers, so nothing changes for now
in the drivers using it, although it enables us to change those more
easily in the future if we want to.

This work is also one of the missing pieces that are required to eventually
build ARM kernels for multiple platforms, which is currently prohibited
(amongs other things) by the fact that you cannot have more than one
driver exporting the pwm functions.
