Subject: [PATCH] ASoC: cs35l32: add missed regulator_bulk_disable in remove

The driver forgets to call regulator_bulk_disable() in remove like that
in probe failure.
Add the missed call to fix it.

This is a similar situation to the one Charles pointed out - the driver
is using runtime PM to manage the regulators so unless the device is
active when removed the regulators won't be enabled.
