Changes in v2:
- Added devicetree bindings documentation

Changes in v3:
- Split 'gcnt' into a separate patch
- Added the new entries to Makefiles, Kconfig & board.c in sorted order
- Used "qcom,ipq40xx" instead of "qcom,ipq40xx-r3pc" in board.c

Changes in v4:
- Renamed IPQ40xx as IPQ4019
- Moved kconfig and defconfig enablement to separate patch
- Dropped Documentation/devicetree/bindings/qcom.txt
