Subject: [PATCH 100/137] arm64: dts: ipq8074: add reserved memory nodes

IPQ8074 has multiple reserved memory ranges, if they are not defined
then weird things tend to happen, board hangs and resets when PCI or
WLAN is used etc.

So, to avoid all of that add the reserved memory nodes from the downstream
5.4 kernel from QCA.
This is their default layout meant for devices with 1GB of RAM, but
devices with lower ammounts can override the Q6 node.
