Adds support for loading Linux kernels through FIT payloads. This has
been implemented as an assembly function in order to simplify dealing
with some of the intricacies of loading a kernel (such as needing to
jump to the kernel in ARM mode and the kernel ABI).
TEST: Booted a FIT image containing a 5.4 kernel and initramfs on the
Beaglebone Black.
