Move program_hpx_type0(), program_hpx_type1(), etc., and enums
hpx_type3_dev_type, hpx_type3_fn_type and hpx_type3_cfg_loc to
drivers/pci/pci-acpi.c as these functions and enums are ACPI-specific.

Move structs hpx_type0, hpx_type1, hpx_type2 and hpx_type3 to
drivers/pci/pci.h as these are shared between drivers/pci/pci-acpi.c and
drivers/pci/probe.c.
