[MOD] Remapping 3 button earphones

This is only applicable to custom roms. So far, i've remapped the buttons to work as supposed:
1) Skip music with long press on volume button on earphones.
+ => next
- => previous
2) Volume control on single press


Tested Earphone:
Xiaomi Piston v2 and v3

Steps:
1) Navigate to /system/usr/keylayout Root explorer
2) overwrite generic.kl
