Given the last documented register is at offset 0x209C, the region above is too
small (also in the example in the DT bindings).
But due to MMU granularity, it will be accessible anyway.

reg = <0xe8210000 0x3000>;

I assume the mandatory "remote-endpoint" property will come with the board
(GR-Peach) DTS patch?
