Ah, I saw this after I posted my comments to patch #1.  I guess this
is the same as this node we have in our cheza board file downstream
(need to get that posted upstream soon):

rmtfs@88f00000 {
  compatible = "qcom,rmtfs-mem";
  reg = <0x0 0x88f00000 0x0 0x800000>;
  no-map;

  qcom,client-id = <1>;
};

That brings up a few things:

1. You should add a node label here.  This allows us to act on the
node more easily from board files, like setting it to disabled or
changing it.

2. In https://crrev.com/c/1119572, the argument was made that the size
of this carveout is board-specific.  That makes it hard to put it in
sdm845.dts.
