pwm: bcm-iproc: Simplify using devm functions
With devm_clk_get_enabled() the call to clk_disable_unprepare() can be
dropped from the error path and the remove callback. With
devm_pwmchip_add() pwmchip_remove() can be dropped. Then the remove
callback is empty and can go away, too.
Also use dev_err_probe() for simplified (and improved) error reporting.
