soc/intel/common/block: Add Intel VGA early graphics support

This patch introduces an early graphics driver which can be used in
romstage in cache-as-ram mode. The implementation relies on
`libgfxinit' and provide VGA text mode support.

SoCs wanting to take advantage of this driver must implement the
`early_graphics_soc_panel_init' function to set the panel power
sequence timing parameters.
