1b8bd17c2d ath79: lzma-loader: allow setting custom kernel magic
...and max flash offset

The mtdsplit parser was recently refactored
to allow the kernel to have custom image header magic.

Let's also do this for the lzma-loader

For example:
When implemented together,
this allows the kernel to "appear" to be a rootfs
by OEM software in order to write an image
that is actually kernel + rootfs.

At the same time,
it would boot to openwrt normally
by setting the same magic in DTS.

Both of the variables
have a default value that is unchanged
when not defined in the makefiles

This has no effect on the size of the loader
when lzma compressed.

071a637276 ath79: move lzma-loader to the end of available RAM
In certain cases, the uncompressed initramfs image will overwrite
the lzma-loader, which is currently only 10 MB away from kernel image
start. To prevent this, change LZMA_TEXT_START to 24 MB, so loader
and compressed image have 8 MB at the end of RAM and uncompressed
image has 24 MB available.

This is only enabled for ath79 at the moment, as there we can be sure
that all devices have 32+ MB RAM and TARGET_INITRAMFS_COMPRESSION_LZMA
is not enabled there.

Despite, since lzma-loader is currently build specifically for ath79
anyway, there is no need to re-specify LOADADDR and LZMA_TEXT_START
in image/Makefile, so the values are set directly in
image/lzma-loader/Makefile and the overwrite in image/Makefile is
removed.

ath79: lzma-loader: sync with ar71xx target
Import all improvements made in the lzma-loader since development on the
ath79 target started.

This also reverts fe594bf90d ("ath79: fix loader-okli, lzma-loader"), as
is obsoleted by 2ad60168b6af ("ar71xx: lzma-loader: move padding workaround
to gzip step").

Likely, many of the changes should be ported to the ramips lzma-loader as
well, but I don't have a device to test this.

fe594bf90d ath79: fix loader-okli, lzma-loader
booting will hang most of the times on tl-wr1043nd-v1 without a KERNEL_CMDLINE value
add anything as a placeholder as kernel command line is taken from DTS

53c474abbd ath79: add new OF only target for QCA MIPS silicon
This target aims to replace ar71xx mid-term. The big part that is still
missing is making the MMIO/AHB wifi work using OF. NAND and mikrotik
subtargets will follow.
