arm64: dts: broadcom: amend the comment about the role of BCM2712 board DTS

Browse source

Current board DTS for Raspberry Pi5 states that bcm2712-rpi-5-b.dts
should not be modified and all declarations should go in the overlay
board DTS instead (bcm2712-rpi-5-b-ovl-rp1.dts).

There's a caveat though: there's currently no infrastructure to reliably
reference nodes that have not been declared yet, as is the case when
loading those nodes from a runtime overlay. For more details about
these limitations see [1] and follow-ups.

Change the comment to make it clear which DTS file will host specific
nodes, especially the RP1 related nodes which should be customized
outside the overlay DTS.
