Upgrading to 23.05.2

* ipq40xx EA6350v3, EA8300, MR8300 and WHW01 require tweak to the U-Boot environment on update from 22.03 to 23.05. Refer to the Device wiki or the instruction on sysupgrade on how to do this change. Config needs to be reset on sysupgrade.


Known issues
============

* lantiq/xrx200 target shows error messages in DSA switch configuration of the integrated GSWIP switch. (see: https://github.com/openwrt/openwrt/pull/13200)
* OpenWrt 23.05.2 was signed with the wrong signing keys. The keys from OpenWrt snapshot were used for OpenWrt 23.05.2 including the release candidates. A later OpenWrt 23.05 service release will use a different key.
