Subject: [RFC Patch net-next 9/9] net: dsa: microchip: add the phylink get_caps
This patch add the support for phylink_get_caps for ksz8795 and ksz9477
series switch. It updates the struct ksz_switch_chip with the details of
the internal phys and xmii interface. Then during the get_caps based on
the bits set in the structure, corresponding phy mode is set.
