cxl: Move bare-metal specific code to specialized files
Move a few functions around to better separate code specific to bare-metal environment from code which will be commonly used between guest and bare-metal. Code specific to bare-metal is meant to be in native.c or pci.c only. It's basically anything which touches the card p1 registers, some p2 registers not needed from a guest and the PCI interface.
