ASoC: ts3a227e: Remap keys to match Android headset specification

Browse source 
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
