[PATCH 02/18] mfd: adp5585: enable oscilator during probe

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

From: Nuno Sá <nuno.sa@analog.com>

Make sure to enable the oscillator in the top device. This will allow to
not control this in the child PWM device as that would not work with
future support for keyboard matrix where the oscillator needs to be
always enabled (and so cannot be disabled by disabling PWM).
