Trusted Firmware now adds the /reserved-memory subnode to the DT at runtime[1], putting in the right values.
Drop our hard-coded version, as this might clash with the actual values (which have also changed), and rely on TF-A to add the node.

If the same fix same available in Linux add SHA1 on the commit message otherwise keep /delete-node on -u-boot.dtsi. This how we are maintaining sofar at least on sunxi.
this DT is not in Linux yet. As this is a new SoC, we have to start at some point, and getting TF-A, Linux and U-Boot patches merged at the same time is virtually impossible. Ideally we have some bootloader support first, so that people can test the kernel patches, for instance.
So this DT is a tentative one, just here to make U-Boot happy. It is expected to change, and will be synced once it's merged into Linux.
As mentioned, the TF-A patches were changed after the U-Boot patches were merged, so this node was needed back then, but is obsolete now.
Cheers, Andre
