[ARM] 3854/2: S3C2410 - add machine type for AML M5900 series (resubmitted)

Add the AML M5900 series to the list of supported machines in the
arch/arm/mach-s3c2410 directory. This ensures the core peripherals
are registered, and the timer source is configured. if selected in
the kernel config the framebuffer registers and mtd partition
information are set.  This version of the patch has corrected
formatting and removed the legacy procfs directory entry.
