pwm: Convert to devm_ioremap_resource()
...
Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

pwm: Check for negative duty-cycle and period
...
Make sure the duty-cycle and period passed in are not negative. This
should eventually be made implicit by making them unsigned. While at
it, the drivers' .config() implementations can have the equivalent
checks removed.

pwm: pxa: Propagate pwmchip_remove() error
...
If the pwmchip_remove() call fails, propagate the error to the driver's
remove callback. This is required to prevent the module from being
unloaded if a PWM provided by the driver is still in use.
