ipq40xx: net: ethernet: edma: use generic ksettings functions

Since we now have a proper PHY driver for QCA807x and AR803x has already
been supported properly there is no need for the driver to be poking
on PHY registers for ethtool ops.

So, lets simply use the generic
phy_ethtool_ksettings_get/phy_ethtool_ksettings_set functions.

This also has the advantage of properly populating stuff other than
speeds like, transceiver type, MDI-X etc.
