The GPIO line connecting to the reset signals of the GS1900-24E(A1)'s external ICs (RTL8218B phys and RTL8231 expander) cannot be asserted by the MDIO subsystem, as the reset is shared between busses. To prevent users from accidentally asserting the reset line, a GPIO hog is created to permanently de-assert the signal, reliably keeping the phys and GPIO expanders on.
