phy: make some bits preserved while setup forced mode When tested the PHY SGMII Loopback: 1.set the LOOPBACK bit, 2.set the autoneg to AUTONEG_DISABLE, it calls the genphy_setup_forced which will clear the bit. The BMCR_LOOPBACK bit should be preserved. As Florian pointed out that other bits should be preserved too. So I make the BMCR_ISOLATE and BMCR_PDOWN as well.
