A .dtsi is an include file, not the final thing for any given device,
for that you need a .dts (which is compiled into a .dtb).

Assuming orion5x-linkstation.dtsi is correctly relating to your
platform you would appear to want one of:
    $ git grep orion5x-linkstation.dtsi arch/arm/boot/dts/*.dts
    arch/arm/boot/dts/orion5x-kuroboxpro.dts:#include "orion5x-linkstation.dtsi"
    arch/arm/boot/dts/orion5x-linkstation-lsgl.dts:#include "orion5x-linkstation.dtsi"
    arch/arm/boot/dts/orion5x-linkstation-lswtgl.dts:#include "orion5x-linkstation.dtsi"

(Or something else not yet present in the kernel tree.)

Of the three above orion5x-kuroboxpro.dts and orion5x-linkstation-
lswtgl both set ports to 2 using:

    &sata {
            nr-ports = <2>;
    };

which overrides the defaults from the dtsi. You mentioned kurobox_pro-
setup.c so perhaps orion5x-kuroboxpro.dts is the one you want?
