Re: [PATCH v2 0/3] net: stmmac: dwmac-rk: fixes for Wake-on-Lan on RK3288

In order to support Wake-On-Lan when using the RK3288 integrated MAC
(with an external RGMII PHY), we need to avoid shutting down the regulator
of the external PHY when the MAC is suspended as it's currently done in the MAC
platform code.
As a first step, create independant callbacks for suspend/resume rather than
re-using exit/init callbacks. So the dwmac platform driver can behave differently
on suspend where it might skip shutting the PHY and at module unloading.
Then update the dwmac-rk driver to switch off the PHY regulator only if we are
not planning to wake up from the LAN.
Finally add the PMT interrupt to the MAC device tree configuration, so we can
wake up the core from it when the PHY has received the magic packet.

Changes since v1:
  * rename 'powered_down' variable into 'suspended'.
  * fix the logic recording the PHY suspended state according to Heiko comments.

Series applied to net-next, thanks.
