misc/pvpanic: Make 'pvpanic_probe()' resource managed
Simplify code and turn 'pvpanic_probe()' into a managed resource version.
This simplify callers that don't need to do some clean-up on error in the
probe and on remove.
Update pvpanic-mmio.c and pvpanic-pci.c accordingly.
'pvpanic_remove()' don't need to be exported anymore.

Add support for pvpanic PCI device added in qemu [1]. At probe time, obtain the
address where to read/write pvpanic events and pass it to the generic handling

unmap base address and disable PCI device.
