Introduce a new event to signal that the live tree has been built,
allowing boards to perform fixups on the tree before devices are bound.
Crucially this allows for devices to be enabled or disabled, but also
allows for properties that are parsed during the bind stage to be
modified (such as dr_mode for dwc3).

With this in place, mach-snapdragon is switched over to use the event
and some hacky U-Boot specific DT overrides (which had to be undone
prior to booting an image) are removed in favour of fixing up the
livetree (which is not passed on to further boot stages).

Finally, some minor fixes are made for the QCM2290 RB1 board, the sdcard
is enabled and it now uses USB host mode in U-Boot like it's bigger
sibling the RB2.

Changes in v2:
- Rename EVT_OF_LIVE_INIT to EVT_OF_LIVE_BUILT
- Pass the root node through as event data in EVT_OF_LIVE_BUILT
- Handle errors from event_notify()
- Additional minor fixes to mach-snapdragon/of_fixup.c
- Link to v1: https://lore.kernel.org/r/20250409-livetree-fixup-v1-0-76dfea80b07f@linaro.org
