Add support for EOS 70D 1.1.1 (both revisions)
Created originally on Bitbucket by nikfreak
I separated both known 70D firmware revisions.
70D_111A is known as the "new revision" and 70D_111B is called "old revision" on the forums.
Pull request modifies several parts of the makefile system like seen on 5D3-113-and-123 branch (PLATFORM_MAP_CONFUSES_THE_MAKEFILES) But this doesn't really clean up the according platform dirs when running "make clean" in root dir
