pi refuses to use new firmware every boot

[George Vatsis]

Every boot no matter what I try I get

New boot assets in /boot/firmware/new failed. Fallen back to known good
state. Use piboot-try --reset-new to re-test boot assets. If you are able
to determine the boot failure is due to a bug, please file an issue:
