[PATCH 2/8] hw/misc/pvpanic: Cosmetic renaming

[Mihai Carabas <mihai.carabas@oracle.com>]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

To ease the MMIO device addition in the next patch, rename:
- ISA_PVPANIC_DEVICE -> PVPANIC_ISA_DEVICE.
- PVPanicState -> PVPanicISAState.
- TYPE_PVPANIC -> TYPE_PVPANIC_ISA.
- MemoryRegion io -> mr.
