[PATCH v8 0/3] net: stmmac: dwmac-sophgo: Add phy interface filter

[Inochi Amaoto <inochiama@gmail.com>]

As the SG2042 has an internal rx delay, the delay should be remove
when init the mac, otherwise the phy will be misconfigurated.

Since this delay fix is common for other MACs, add a common helper
for it. And use it to fix SG2042.
