Another patch provided here changes the clock referenced in the device tree. 
Since I changed the I2C clock source in a previous patch, it makes sense to 
actually use the resulting clock in the device tree.

The driver is an adaptation of the JZ4740 driver in terms of boilerplate, but 
it incorporates the mechanisms of the legacy drivers. So, unless I carried 
things forward incorrectly, the techniques should be familiar.

A brief review of the PWM documentation gave nothing else away here.
