The fixed_phy_get_gpiod function() returns NULL, it doesn't return error
pointers, using NULL checking to fix this.i

This patch prevents systems using fixed PHY devices from successfully
registering, especially when those systems have a fixed PHY that does
not use a GPIO:
[ 5.971952] brcm-systemport 9300000.ethernet: failed to register
fixed PHY
[ 5.978854] brcm-systemport: probe of 9300000.ethernet failed with
error -22
[ 5.986047] brcm-systemport 9400000.ethernet: failed to register
fixed PHY
[ 5.992947] brcm-systemport: probe of 9400000.ethernet failed with
error -22
Please drop it for now until it can be investigated. Thanks!
