arm/imx21: add kbuild support for the Freescale i.MX21
* adds Kconfig variables * specifies different physical address for i.MX21 because of the different memory layouts * disables support for UART5/UART6 in the i.MX serial driver (the i.MX21 doesn't have those modules) Based on code from "Martin Fuzzey" <mfuzzey@gmail.com> Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
