Add OPROM mapping support to coreboot

This allows to add a PCI ID mapping function for option roms so that the same
    option rom can be used for a series of devices / PCI IDs. Intel and AMD often
    use the same option rom for a number of PCI devices with differend IDs.

A function to implement such a mapping could look like this (or anything else
    appropriate):

/* some vga option roms are used for several chipsets but they only have one
     * PCI ID in their header. If we encounter such an option rom, we need to do
     * the mapping ourselfes
     */

u32 map_oprom_vendev(u32 vendev)
    {
        u32 new_vendev=vendev;

switch(vendev) {
        case 0xa0118086:
            new_vendev=0xa0018086;
            break;
        }

return new_vendev;
    }
