pvpanic-mmio.c and pvpanic-pci.c share a lot of code.
Refactor it into pvpanic.c where it doesn't have to be kept in sync
manually and where the core logic can be understood more easily.
No functional change.

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.

There is no need to use GFP_ATOMIC in a probe function. Use GFP_KERNEL
instead.

There is no error handling path in the probe function.
Switch to managed resource so that errors in the probe are handled easily
and simplify the remove function accordingly.

Create the mecahism that allows multiple pvpanic instances to call
pvpanic_probe and receive panic events. A global list will retain all the
mapped addresses where to write panic events.

Split-up generic and platform dependent code in order to be able to re-use
generic event handling code in pvpanic PCI device driver in the next patches.
The code from pvpanic.c was split in two new files:
- pvpanic.c: generic code that handles pvpanic events
- pvpanic-mmio.c: platform/bus dependent code
