target: msm8610: Add GPIO value translation for reset sequence
8610 target uses different GPIO API to enable/disable the GPIO
compared to 8x26/8974. 8610 target has to translate the GPIO
HIGH and LOW value from other target and needs to set the correct
value in its API. That will allow the target to use any 8x26/8974
panel.
