From: Rohit Raj <rohit.raj@nxp.com>
This patch adds support to get/set link speed, duplex and
autoneg mode status from/to PHY. Enahnce device capabilities
to advertise all supported link speeds according to mac type.
Also enables fallback support for get link status api where
kernel support is missing.
