staging: sm7xxfb: sm7xx becomes sm7xxfb
Rename sm7xx driver to sm7xxfb. Fix Kconfig and Makefile to fit the new change. Changes are coherent with the rest of stable framebuffer drivers. TODO updated. Signed-off-by: Javier M. Mellid <jmunhoz@igalia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
