This patch adds a configuration menu for the VGA ROM, it also allow the creation of a PCI header so the ROM can be extracted from a PCI device.

One other note on this - can't _rom_pci_data be declared in the C code as:
struct pci_data rom_pci_data VAR16VISIBLE = { .vendor = CONFIG_VGA_VID, .device = CONFIG_VGA_DID, .dlen = 0x18, .class_hi = 0x300, ... };
The PCI firmware specification only requires the PCI header to be located in the first 64KB of the option ROM image, I don't know if there's a way we can enforce that if it is declared in C.
