From Documentation phy resume triggers phy reset and restart
auto-negotiation. Add a dedicated function to wait reset to finish as
it was notice a regression where port sometime are not reliable after a
suspend/resume session. The reset wait logic is copied from phy_poll_reset.
Add dedicated suspend function to use genphy_suspend only with QCA8337
phy and set only additional debug settings for QCA8327. With more test
it was reported that QCA8327 doesn't proprely support this mode and
using this cause the unreliability of the switch ports, especially the
malfunction of the port0.
