kernel: fix AT8032 PHY phy id mask 

Don't mask bit 4 of the AT8022 phy id. If bit 4 of the AT8022 phy id
(0x004dd023) is masked, it will match the phy id of the AR8327 switch
(0x004dd033) as well.

It results in applied at803x driver settings/callbacks, which will at
least limit the AR8327 phys to 100MBit operation instead of the possible
1000MBit.
