imx: add imx8m support 

Add imx8m support:
 - add a cortexa53 subtarget to imx
 - move ARCH and KERNELNAME to subtargets
 - account for kernel modules that are not used for cortexa53

No device-specific targets or firmware images are created yet but all
imx8m* dtbs will be built.

enabling CONFIG_TARGET_ROOTFS_INITRAMFS results in
openwrt-imx-cortexa53-imx8m-initramfs-kernel.bin which has been
successfully booted on an imx8mm-evk using the following:

u-boot=> tftpboot $fdt_addr_r image-imx8mm-evk.dtb && \
tftpboot $kernel_addr_r openwrt-imx-cortexa53-imx8m-initramfs-kernel.bin && \
booti $kernel_addr_r - $fdt_addr_r
