[PATCH 03/18] pwm: adp5585: don't control OSC_EN in the pwm driver

[Nuno Sá via B4 Relay <devnull+nuno.sa.analog.com@xxxxxxxxxx>]

From: Nuno Sá <nuno.sa@xxxxxxxxxx>

The adp5585 is a Multi Function Device that can also be a gpio
controller and as it turns out, when OSC_EN is not set, we can't
reliably read the gpio value when it's configured as input. Hence,
OSC_EN will be set during probe by the parent device (and cleared on
unbind).

Moreover, we'll add support for the keymap matrix (input device) which
definitely needs OSC_EN to be set and so, we cannot afford that disabling
the PWM output also breaks the keymap events generation.
