Subject: [PATCH v1] net: phy: micrel: add KSZ8795 ethernet switch

This is add support for the PHYs in the KSZ8795 5port managed switch.

It will allow to detect the link between the switch and the soc
and uses the same read_status functions as the KSZ8873MLL switch.

This ethernet switch have unfortunately the same phy id as KSZ8051.
