Subject: [PATCH net-next 1/2] net: stmmac: Add support for multiple phy interface for integrated PCS

In case of integrated PCS ethernet does't have external PCS driver.
Currently stmmac supports multiple phy interfaces if there is external PCS.
Add a function to support mupliple phy interfaces when PCS is integrated.
