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.

Thanks. MI4_FORMAT is wrong (that's only for the non-ipod PP targets),
but the BOOTFILE definitions will be used - both in the bootloader and
main Rockbox.

Sure, but as this is still a work-in-progress, I wanted to keep the code
as close to the OF as possible, including all silliness - to make
finishing (and double-checking) the work easier. It can be
cleaned/optimised later, once it works.

OK, thanks.

Maybe, but the telechips part of that file is common across both tcc77x
devices that use the ssd1815 (m200v1 and Logik DAX), so the CPU seemed
the appropriate #if there.

And since we only have one as3525 device using it, so I decided to use
the CPU there as well.

But it's easily changed if a second as3525 device appears that uses the
ssd1815, or if we want to merge the Clip's ssd1303 driver.

Dave.
