Subject: [PATCH 5.7 418/477] arm64: dts: realtek: rtd129x: Use reserved-memory for RPC regions

From: Andreas Färber <afaerber@...e.de>

commit 690677c22d5fa5dfdaa609a1739b75fdfb1c4a24 upstream.

Move /reserved-memory node from RTD1295 to RTD129x DT.
Convert RPC /memreserve/s into /reserved-memory nodes.

Fixes: 72a7786c0a0d ("ARM64: dts: Add Realtek RTD1295 and Zidoo X9S")
Fixes: f8b3436dad5c ("arm64: dts: realtek: Factor out common RTD129x parts")
