rom loader: make vga+rom loading configurable.
The rom_add_vga() and rom_add_option() macros are transformed into functions. They look at the new rom_enable_driver_roms variable and only do something if it is set to non-zero, making vga+option rom loading runtime option. pc_init() sets rom_enable_driver_roms to 1. With this in place we can move the rom loading calls from pc.c to the individual drivers. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
