The current patch are used downstream on the OpenWrt ipq806x target that
is a mix of legacy (what this affects) and non legacy targets. (old
bootloader support loading DTB from the image and older ones require it
to be appended)

I think I need some help from the community to test this.

I can also move these patches to our "generic" target on OpenWrt so that
they will be enabled by every arm target we support.

Anyway thanks for the feedback, my only concern was that I messed
submitting the patch on the tracking system. Hope community can help
with this since it's a big feature for legacy devices that was broken
from a looong time (and only solution currently is to hardcode the PHY
offset values)
