The type definition of struct pci_setup_rom in <asm/pci.h> requires
struct setup_data from <asm/bootparam.h>. Many drivers include
<linux/pci.h>, but do not use boot parameters. Changes to bootparam.h
or its included header files could easily trigger a large, unnecessary
rebuild of the kernel.
Moving struct pci_setup_rom into its own header file avoids including
<asm/bootparam.h> in <asm/pci.h>. Moving struct_efi_setup_data allows
to unify duplicated definition of the data structure in a single place.
