mxc: Add support for the Babbage board (i.MX5)
Babbage is a reference board from Freescale for their i.MX51 SoC. Add board definition, Kconfig and Makefiles to enable Freescale i.MX51 processor and Babbage board. Boot tested on a Babbage2.5 board Signed-off-by: Amit Kucheria <amit.kucheria@canonical.com>
