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 setup_data and related code into its own header file
avoids including <asm/bootparam.h> in <asm/pci.h>. Instead include the
new header <asm/screen_data.h> and remove the include statement for
x86_init.h, which is unnecessary but pulls in bootparams.h.
