commit 2f35ad5db4e11e3843764c8bf8d982e4a174f4a1

Add default map_oprom_vendev() for AMD Family 14h processors.

AMD supplies their video bios for the Family 14h processor line
    with Vendor ID: 1002, Device ID: 9802.  This rom should work for
    Device IDs 9802-9809.  This patch maps all those device IDs to
    0x9802 so coreboot will be able to load the vbios.  If a vbios
    rom using the ACTUAL Device ID is loaded, this function will not
    be called.
    This file should contain of all Family 14h Graphics PCI IDs so
    that they don't need to be overridden on a per mainboard basis.
