Support kernel_noload uImage type
Do not trigger an error when loading a uImage with the
IH_TYPE_KERNEL_NOLOAD type. These images do not need to be copied to
their load address before being executed.
All archs (excepted PPC) do not use the uImage load and entry point
parameters, so their current behavior needs not be changed further than
just accepting the image type.
Tested and validated on ARM.
