drivers/xgi: Fix usage of NGI Kconfig options
This driver reinvented MAINBOARD_DO_NATIVE_VGA_INIT in a very special
way: If it wasn't set, perform native gfx init in textmode, if it was
set, perform native gfx init in linear framebuffer mode. Test for
LINEAR_FRAMEBUFFER instead and make the native gfx init optional.
Also, make Kconfig reflect the actual behaviour.
