In order to get rid of the global namespace for PWM devices, this commit
provides an alternative method, similar to that of the regulator or
clock frameworks, for registering a static mapping for PWM devices. This
works by providing a table with a provider/consumer map in the board
setup code.
A subsequent patch will add a generic PWM API driver for the Tegra PWFM
controller, supporting all four PWM devices with a single PWM chip. The
device will be named tegra-pwm and only one clock needs to be provided.
