net: phylink: add suspend/resume support
Joakim Zhang reports that Wake-on-Lan with the stmmac ethernet driver broke when moving the incorrect handling of mac link state out of mac_config(). This reason this breaks is because the stmmac's WoL is handled by the MAC rather than the PHY, and phylink doesn't cater for that scenario. This patch adds the necessary phylink code to handle suspend/resume events according to whether the MAC still needs a valid link or not. This is the barest minimum for this support.
