image: android: allow booting lz4-compressed kernels
According to Android image format [1], kernel image resides at 1 page
offset from the boot image address. Grab the magic number from there
and allow U-Boot to handle LZ4-compressed KNL binaries instead of
hardcoding compression type to IH_COMP_NONE. Other compression types,
if needed, can be added later.
Tested on H3ULCB-KF using the image detailed in [2].
[1] Excerpt from include/android_image.h
+-----------------+
| boot header | 1 page

| kernel | n pages

| ramdisk | m pages
