[PATCH 16/16] ASoC: cs42l42: Always enable TS_PLUG and TS_UNPLUG interrupts

[Richard Fitzgerald]

The headset type detection must run to set the analogue switches
correctly for the attached headset type. Without this only headsets
with wiring matching the chip default will have a functioning mic.

commit c26a5289e865 ("ASoC: cs42l42: Add support for set_jack calls")
moved the interrupt unmasking to the component set_jack() callback.
But it's not mandatory for a machine driver to register a struct
snd_soc_jack handler. Without a registered handler the type detection
would not have run and so the mic would not work on some types of
headset.

This patch restores the unmasking of TS_PLUG and TS_UNPLUG interrupts
during probe.
