Revert "arm64: dts: amlogic: add missing ethernet reset ID"

Browse Source 
commit 19f6fe976a upstream.

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 f3362f0c18 while we find
and acceptable solution to cleanly reset the Ethernet MAC.
