Add imx8m support:
- add a cortexa53 subtarget to imx
- move ARCH and KERNELNAME to subtargets
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

v2:
- fix build failure regarding ubifs image generation
- remove kernel patches (these all go away when we move to 6.1
and I've already submitted a series to add 6.1 support to imx)
- add a generic imx8m device that picks up imx8m dtb's
- show example of how I'm booting this in commit log
