Subject: [PATCH] sdk_dpaa: adapt to kernel 5.1.0 rc1

Apply fixes corresponding to the following upstream patches:
3c1bcc8 net: ethernet: Convert phydev advertize and supported from u32 to link mode
1e562c8 ptp_qoriq: make structure/function names more consistent
70814e8 net: ethernet: Add helper for set_pauseparam for Asym Pause
22b7d29 net: ethernet: Add helper to determine if pause configuration is supported
