The RZ/G2M (a.k.a. r8a774a1) comes with two clusters of
processors, similarly to the r8a7796.
The first cluster is made of A57s, the second cluster is
made of A53s.

The operating points for the cluster with the A57s are:

 Frequency | Voltage
-----------|---------
 500 MHz   | 0.82V
 1.0 GHz   | 0.82V
 1.5 GHz   | 0.82V

The operating points for the cluster with the A53s are:

 Frequency | Voltage
-----------|---------
 800 MHz   | 0.82V
 1.0 GHz   | 0.82V
 1.2 GHz   | 0.82V

It is incorrect to specify the no-ether-link property for the AVB device on
the Ebisu board. This is because the property should only be used when a
board does not provide a proper AVB_LINK signal. However, the Ebisu board
does provide this signal.

As per 87c059e9 ("arm64: dts: renesas: salvator-x: Remove renesas,
no-ether-link property") this fixes a bug:

    Steps to reproduce:
    - start AVB TX stream (Using aplay via MSE),
    - disconnect+reconnect the eth cable,
    - after a reconnection the eth connection goes iteratively up/down
      without user interaction,
    - this may heal after some seconds or even stay for minutes.

    As the documentation specifies, the "renesas,no-ether-link" option
    should be used when a board does not provide a proper AVB_LINK signal.
    There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS
    and ULCB starter kits since the AVB_LINK is correctly handled by HW.

    Choosing to keep or remove the "renesas,no-ether-link" option will have
    impact on the code flow in the following ways:
    - keeping this option enabled may lead to unexpected behavior since the
      RX & TX are enabled/disabled directly from adjust_link function
      without any HW interrogation,
    - removing this option, the RX & TX will only be enabled/disabled after
      HW interrogation. The HW check is made through the LMON pin in PSR
      register which specifies AVB_LINK signal value (0 - at low level;
      1 - at high level).

    In conclusion, the present change is also a safety improvement because
    it removes the "renesas,no-ether-link" option leading to a proper way
    of detecting the link state based on HW interrogation and not on
    software heuristic.
