[Qemu-arm] [PATCH V7 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:

v3 --> v4
  patch 1,2 no modification.
  patch 3, add TYPE_PANIC_MMIO for distinguishing different bus device,

  patch 5, newly added.

v4 --> v5
