Uwe Kleine-König 157cf2b51d pwm: bcm2835: Make sure the channel is enabled after pwm_request() ...

[ Upstream commit cda323dbda ]

The .free callback cleared among others the enable bit PWENx in the
control register. When the PWM is requested later again this bit isn't
restored but the core assumes the PWM is enabled and thus skips a
request to configure the same state as before.

To fix that don't touch the hardware configuration in .free(). For
symmetry also drop .request() and configure the mode completely in
.apply().
