Stable request: net: stmmac: resume rx clocking

[Jon Hunter]

Hi Greg, Sasha,

Updates to the stmmac networking driver in Linux v6.14 exposed some 
issues with resuming the driver on platforms such as the Tegra186 Jetson 
TX2 board. This is why the suspend test has been failing on this 
platform for the linux-6.14.y updates ...

  Test failures:    tegra186-p2771-0000: pm-system-suspend.sh

Russell has provided some fixes for this that are now in the mainline 
and so I would like to integrate the following changes to linux-6.14.y ...

  f732549eb303 net: stmmac: simplify phylink_suspend() and
   phylink_resume() calls
  367f1854d442 net: phylink: add phylink_prepare_resume()
  ef43e5132895 net: stmmac: address non-LPI resume failures properly
  366aeeba7908 net: stmmac: socfpga: remove phy_resume() call
  ddf4bd3f7384 net: phylink: add functions to block/unblock rx clock stop
  dd557266cf5f net: stmmac: block PHY RXC clock-stop

I had a quick look to see if we can backport to linux-6.12.y but looks 
like we need more commits and so for now just target linux-6.14.y.

Jon
