The new version of the HW supports MSI interrupts instead of wired
interrupts. The MSI interrupts are especially useful for the guest machine
execution. The wired interrupts usually trap to the hypervisor and then are
relayed to the actual interrupt.

The MSI interrupts can be directly fed into the interrupt controller.

Adding a new OF compat string (qcom,hidma-1.1) and ACPI string (QCOM8062)
to distinguish newer HW from the older ones.

v4:
* device tree binding update to refer to msi.txt

v3:
* day 0 fix for when ACPI is not compiled in
* https://www.spinics.net/lists/arm-kernel/msg532179.html

v2:
https://patchwork.kernel.org/patch/9326399/
* Documentation update for DT bindings
* Rebased to slave-next
* Dropped dmaengine: qcom_hidma: eliminate processed variables. Replaced it
  with dmaengine: qcom_hidma: protect common data structures

v1:
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-July/444167.html
* initial implementation
