bootsource: create arch independent bootsource framework
This patch seperates the imx independent from the arch independent code. The following functions and enums are renamed: - imx_bootsource() -> bootsource_get() - imx_set_bootsource() -> bootsource_set() - enum imx_bootsource -> enum bootsource Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
