AArch64 images are not self-decompressing, thus usually much larger. Boot times can be reduced by compressing them in FIT and uImages. This commit is a backport of commit a725d188b5 (kernel-uboot: compress arm64 kernels) and commit 60bc7e180e (kernel-uboot: remove useless special casing of arm64 Image) from master. Both commit were melted into one to avoid some useless churn.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
