ts3a227e does not trigger interrupt to report jack status when system
boots from warm reset because ts3a227e's power remains on during warm reset.
Read jack status at probe to get current jack status.
Note that if system boots from EC reset, then this issue will not
happen.

The TS3A227E is an autonomous audio accessory detection and
configuration switch that detects 3-pole or 4-pole audio accessories
and configures internal switches to route the signals accordingly.
This chip also has built-in support for the new button standard
described in the Android "Wired audio headset specification" v1.0.
These buttons will be reported on the jack as buttons 0-3 mapped to
KEY_MEDIA, KEY_VOLUMEUP, KEY_VOLUMEDOWN, and KEY_VOICE_COMMAND.
This will be added as an aux_dev and have the jack passed in from the
machine driver.
