ASoC: cs35l41: Undo runtime PM changes at driver exit time

Browse Source 
According to the documentation, drivers are responsible for undoing at
removal time all runtime PM changes done during probing.

Hence, add the missing calls to pm_runtime_dont_use_autosuspend(), which
are necessary for undoing pm_runtime_use_autosuspend().

Note this would have been handled implicitly by
devm_pm_runtime_enable(), but there is a need to continue using
pm_runtime_enable()/pm_runtime_disable() in order to ensure the runtime
PM is disabled as soon as the remove() callback is entered.
