Sander Vanheule cdc92ce560 realtek: hog the GS1900-24E external IC reset line
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.
