wic:mx8: Create wks file for imx8 family using imx-boot

imx8 family boards use u-boot as boot loader in addition to some other
binaries. The final bootloader binary is gathered by mkimage into a file
called imx-boot.

Add the wks file to create the wic image tailored for imx8 family.
Set the wks file as default for all imx8.
