Add a video driver for Intel's broadwell integrated graphics controller. This uses a binary blob for most init, with the driver just performing a few basic tasks.
This driver supports VESA as the mode-setting mechanism. Since most boards don't support driver model yet with VESA, a special case is added to the Kconfig for broadwell. Eventually all boards will use driver model and this can be removed.
