Add a Kconfig option to disable the Integrated Graphics Device (IGD) so that it does not show in the PCI configuration space as a VGA disaplay controller. This gives a chance for U-Boot to run PCI/PCIe based graphics card's VGA BIOS and use that for the graphics console.

The location of the CMC binary is determined by a strap. It must be

put in flash at a location matching the strap-determined base address.

The default base address of 0xfffb0000 indicates that the binary must

be located at offset 0xb0000 from the beginning of a 1MB flash device.
