drm: Move sysfb drivers into separate subdirectory

Browse Source 
The ofdrm and simpledrm drivers are special as they operate on
externally provided framebuffers. Move them into their own sub-
directory. Will let them share common code.

On x86 BIOS or UEFI systems, you should also select SYSFB_SIMPLEFB
