Support PCI based option rom loading
Currently, we preload option roms into the option rom space in memory. This prevents DDIM from functioning correctly which severely limits the number of roms we can support. This patch introduces a pci_add_option_rom() which registers the PCI_ROM_ADDRESS bar which points to our option rom. It also converts over the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this new mechanism. The result is that PXE boot functions even with three unique types of cards.
