Other memory regions in sc7280.dtsi also get referenced but not actually
defined in that file, like mpss_mem and wpss_mem. Alternatively we can
also try and solve this differently, but then we should probably also
adjust mpss and wpss to be consistent.
Apart from either declaring cdsp_mem in sc7280.dtsi or
"/delete-property/ memory-region;" for CDSP I don't really have better
ideas though.
I also imagine these ChromeOS devices will want to enable cdsp at some
point but I don't know any plans there.
