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
