Add e200v2 and m200v2 targets. Move the telechips lcd-ssd1815.c (currently used by Logik DAX and m200v1 ports) driver up in the target tree and share with the m200v2 - as2525 parts contributed by Rafael Carre. Includes the start (but is still very incomplete) of an LCD driver for the e200v2. m200v2 is not yet fully supported by mkamsboot - that will come soon. Also some minor cleanups for the Clip.
