Since 5c72105e29 ("kernel-uboot: allow compression option to be configurable")
it is possible to select kernel compression method, however the resulting
image is always compressed with gzip, so selecting any other method than
gzip results in unbootable images. Add support for lzo for starters, since
that is fast to decompress and useful in low boot time scenarios.
Note that we should likely add some check for unsupported compression
methods. We should also add dependency on lzop-native I think.

While some platforms might choose to compress the kernel by
default especially when boot medium is slow, others want
uncompressed kernel.
The choice of decompression speed vs. load speed is very
platform dependent.
Allow platform to choose the option here.

Since commit a725d188b5 (kernel-uboot: compress arm64 kernels)
arm64 Image files are handled exactly like in the default case, making
this special case pointless. Remove it to make the code simpler.

AArch64 images are not self-decompressing, thus usually much larger.
Boot times can be reduced by compressing them in FIT and uImages.

Image will be generated for arm64, and no compression for Image in u-boot as
well. So we just put the file into the right place for the rest of the build
to find it.

MIPS generates vmlinuz.bin when compression in the kernel build is
enabled, including any necessary objcopy so we can leverage that
and skip our manual invocation of objcopy here. We just have to
put the file into the right place for the rest of the build to
find it.

Building uImage fails when KEEPUIMAGE is not "yes".
Remove wrong removal of linux.bin before compressing it.

Separate the function which prepares the kernel for packing into
uImage into separate class, so this function can be reused by the
fitImage class.
