STM32H7 ethernet pin corrections

These patches were submitted a few months ago, but it was found out
that the default-by-family: [] were missing in the GPIO .yml lines.
This was fixed in this patch.

This patch accounts for different pins for the ETH peripheral
on STM32H7 devices. For example, the Nucleo H743ZI has slightly
different pins than other STM32H7 boards.
