gps: Fork the GPS HAL

For this device's loc_api_v02, we need a version older than the
one at hw/qcom

Change-Id: I855c626faa5fc7de72e57e56aac5ea3b61cfe042
g2: Use QCOM PowerHAL

Preferable that we use the 2.5.18 QC-OPT (I'll open a pull request
at TheMuppets)

g2: Move kernel dependency to common

Change-Id: I597bceb6b4590f5ef230fdc3100feebf235a2577
g2: Clean common NFC

-Current system screws up ALL variants NFC
-Replace libnfc-brcm.conf with stock for d80x and vs980 and move
 to device repos

Brings back deleted CDMA configuration
