Collect some of the memory frame LCD C code.
For this commit: Sansa e200v1, Gigabeat F, Gigabeat S and Mini2440 are changed over. Quite a number of other targets probably can be as well. General LCD code is moved out of the target drivers into drivers/lcd-memframe.c. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31311 a1c6a512-1295-4272-9138-f99709370657
