xen/vga: add the xen EFI video mode support 

In order to add xen EFI frambebuffer video support, it is required to add
xen-efi's new video type (XEN_VGATYPE_EFI_LFB) case and handle it in the
function xen_init_vga and set the video type to VIDEO_TYPE_EFI to enable
efi video mode.

The original patch from which this was broken out from:
