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 compatible string (qcom,hidma-1.1) and ACPI string (QCOM8062) to distinguish newer HW from the older ones.
