Input: pwm-beeper - fix - scheduling while atomic

commit f49cf3b8b4c841457244c461c66186a719e13bcc upstream.

Pwm config may sleep so defer it using a worker.

On a Freescale i.MX53 based board we ran into "BUG: scheduling while
atomic" because input_inject_event locks interrupts, but
imx_pwm_config_v2 sleeps.

Tested on Freescale i.MX53 SoC with 4.6.0.
