[PATCH stable 5.10] Revert "arm64: dts: amlogic: add missing ethernet reset ID"

[Neil Armstrong]

It has been reported on IRC and in KernelCI boot tests, this change breaks
internal PHY support on the Amlogic G12A/SM1 Based boards.

We suspect the added signal to reset more than the Ethernet MAC but also
the MDIO/(RG)MII mux used to redirect the MAC signals to the internal PHY.

This reverts commit f3362f0c18174a1f334a419ab7d567a36bd1b3f3 while we find
and acceptable solution to cleanly reset the Ethernet MAC.

commit 19f6fe976a61f9afc289b062b7ef67f99b72e7b9 upstream.
