ASoC: ts3a227e: Remap keys to match Android headset specification
ts3a227e datasheet says typical key resistance is
key1 50 Ohm
key2 135 Ohm
key3 240 Ohm
key4 470 Ohm
The android headset specification expect buttons impedance:
A (MEDIA) 0-70 Ohm
D (VOICECOMMAND) 110-180 Ohm
B (VOLUMEUP) 210-290 Ohm
C (VOLUMEDOWN) 360-680 Ohm
Thus key mapping should be
key1 - MEDIA
key2 - VOICECOMMAND
key3 - VOLUMEUP
key3 - VOLUMEDOWN
