net: phy: marvell 88e151x: Fix handling of bare RGMII interface type

Browse source 
Commit 68e6ecadc5 ("net: phy: marvell 88e151x: Fix handling of RGMII
interface types") fixed the initialization of 88e151x phys, but made it
so that interfaces of type PHY_INTERFACE_MODE_RGMII had both RX and TX
delay bits cleared. The default (like in m88e1111s_config) is to have
both bits set.

Hence, this patch changes the behavior in the PHY_INTERFACE_MODE_RGMII
case so that both bits are set.
