The old binding variant (the one covering whole DMU block) was
deprecated 3 years ago. Linux kernel was warning when using it for
similar amount of time.
There aren't any known Northstar devices with bootloader providing DT to
operating system. Actually OpenWrt seems to be the only project using
this binding and it always appends DTB to kernel. It has switched to the
non-deprecated binding years ago.
Given there is close to zero chance this breaks anyone's setup it should
more than safe to drop this binding variant after 3 years.

The old binding was covering the whole DMU block space (DMU block
contains CRU block which contains USB PHY). It was a bad design,
overkill and a non-generic solution.
Northstar's USB 2.0 PHY is a small block (part of the CRU MFD) and
binding should be designed to represent that properly. Rework the
binding to map just PHY with the "reg" property and use syscon to
reference shared register that controls block access.
The old binding is deprecated now.
