smsc911x: add external phy detection overrides
On LAN9115/LAN9117/LAN9215/LAN9217, external phys are supported. These
are usually indicated by a hardware strap which sets an "external PHY
detected" bit in the HW_CFG register.
In some cases it is desirable to override this hardware strap and force
use of either the internal phy or an external PHY. This patch adds
SMSC911X_FORCE_INTERNAL_PHY and SMSC911X_FORCE_EXTERNAL_PHY flags so a
platform can indicate this preference via its platform_data.
