====================
net: stmmac: fix timestamp snapshots on dwmac1000

this is the v2 of a small series containing two small fixes for the
timestamp snapshot feature on stmmac, especially on dwmac1000 version.
Those issues have been detected on a socfpga (Cyclone V) platform. They
kind of follow the big rework sent by Maxime at the end of last year to
properly split this feature support between different versions of the
DWMAC IP.
