net: stmmac: Hold rtnl lock in suspend/resume callbacks

Browse source

We need to hold rnl lock in suspend and resume callbacks because phylink
requires it. Otherwise we will get a WARN() in suspend and resume.

Also, move phylink start and stop callbacks to inside device's internal
lock so that we prevent concurrent HW accesses.

Fixes: 74371272f9 ("net: stmmac: Convert to phylink and remove phylib logic")
