misc/pvpanic: split-up generic and platform dependent code 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.

misc/pvpanic: probe multiple instances 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.

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.
