Signed-off-by: Varadarajan Narayanan <varada@xxxxxxxxxxxxxx>
---
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
