imx: decouple sdcard sysupgrade from Apalis boards

Browse Source 
Sysupgrade procedure for i.MX 6 Apalis boards is suitable for most other
i.MX boards booting from eMMC or SD card. Extract the common parts and
decouple the procedure from "apalis" board name in sysupgrade TAR
contents, so the procedure is reusable for i.MX 7 boards.
