From: John Thomson <g...@johnthomson.fastmail.com.au>
Return to using the OpenWrt kernel loader to decompress and load kernel
initram image.
Continue to use the vmlinuz kernel for squashfs.
Mikrotik's bootloader RouterBOOT on some ath79 devices is
failing to boot the current initram, due to the size of the initram image.
On the ath79 wAP-ac:
a 5.7MiB initram image would fail to boot
After this change:
a 6.6MiB initram image successfully loads
This partially reverts commit e91344776b9ba7c864be88d915c9c0df0eb790dd.
An alternative of using RouterBOOT's capability of loading an initrd ELF
section was investigated, but the OpenWrt kernel loader allows larger image.

Fixes: #9954

This should be backported as it fixes non-bootable install media for 22.03
It has seen a couple months of use in master with no report of issues.
