[Qemu-arm] [PATCH V8 00/10] 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:

v3 --> v4
     patch 1,2 no modification.
     patch 3, add TYPE_PANIC_MMIO for distinguishing different bus device,
              virt + isa_pvpanic will abnormally terminate virtual machine.
     patch 4, "pvpanic,mmio" --> "qemu,pvpanic-mmio".
     patch 5, newly added.

v4 --> v5
     patch 1,2 no modification.
     patch 3 delete PvpanicCommonState structure.
     patch 4 VIRT_PVPANIC_MMIO --> VIRT_PVPANIC
             correct VIRT_PVPANIC's overlap start address
     patch 5 no modification.
    
v5 --> v6
     add document.
  
v6 --> v7
     patch 5 modify device name from "PANC" to "PEVT".
     patch 6 modify document description.

v7 --> v8
     add configure interface for pvpanic-mmio
