Merge branch 'phylink_set_mac_pm'

Shenwei Wang says:

====================
net: phylink: add phylink_set_mac_pm() helper

Per Russell's suggestion, the implementation is changed from the helper
function to add an extra property in phylink_config structure because this
change can easily cover SFP usecase too.

Changes in v6:
 - update the fix tag hash and format

Changes in v5:
 - Add fix tag in the commit message

Changes in v4:
 - Clean up the codes in phylink.c
 - Continue the version number
====================
