The new device dts file should be named rk3588-coolpi-cm5-genbook.dts
instead of rk3588-coolpi-genbook.dts, because that would:
(a) follow the "dependency graph" naming scheme, and
(b) make the naming scheme future-proof for some other SoM that
could possibly be made available for the GenBook in the
future, for which the new device dts file would be named
rk3588-coolpi-XYZ-genbook.dts.
