[Qemu-arm] [PATCH V12 0/5] add pvpanic mmio support

[Peng Hao]

The first patches are simple cleanups:
     - patch 1 move the pvpanic device with the 'ocmmon objects' so we compile
               it once for the x86/arm/aarch64 archs,
     - patch 2 simply renames ISA fields/definitions to generic ones.

     Then instead of add/use the MMIO pvpanic device in the virt machine in an
     unique patch, I split it in two distinct patches:
     - patch 3 uses Peng Hao's work, but add the MMIO interface to the existing
        device (no logical change).
     - patch 4 is Peng Hao's work in the virt machine (no logical change).
     - patch 5 add pvpanic device in acpi table in virt machine
     v2 from Peng Hao is:

     add document.

v6 --> v7
     patch 5 modify device name from "PANC" to "PEVT".
