ASoC: arizona-jack: convert into a helper library for codec drivers
Convert the arizona extcon driver into a helper library for direct use
from the arizona codec-drivers, rather then being bound to a separate
MFD cell.
Note the probe (and remove) sequence is split into 2 parts:
1. The arizona_jack_codec_dev_probe() function inits a bunch of
jack-detect specific variables in struct arizona_priv and tries to get
a number of resources where getting them may fail with -EPROBE_DEFER.
2. Then once the machine driver has create a snd_sock_jack through
snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on
the codec component, which will call the new arizona_jack_set_jack(),
which sets up jack-detection and requests the IRQs.
This split is necessary, because the IRQ handlers need access to the
arizona->dapm pointer and the snd_sock_jack which are not available
when the codec-driver's probe function runs.
Note this requires that machine-drivers for codecs which are converted
to use the new helper functions from arizona-jack.c are modified to
create a snd_soc_jack through snd_soc_card_jack_new() and register
this jack with the codec through snd_soc_component_set_jack().
