net: phy: broadcom: Allow BCM54210E to configure APD
BCM54210E/BCM50212E has been verified to work correctly with the auto-power down configuration done by bcm54xx_adjust_rxrefclk(), add it to the list of PHYs working. While we are at it, provide an appropriate name for the bit we are changing which disables the RXC and TXC during auto-power down when there is no energy on the cable.
