Subject: net: mvneta: disable MVNETA_CAUSE_PSC_SYNC_CHANGE interrupt
The PSC sync change interrupt can fire multiple times while the link is
down. As this isn't information we make use of, it's pointless having
the interrupt enabled, so let's disable this interrupt.

Subject: sfp: hack: allow marvell 10G phy support to use SFP
Allow the Marvell 10G PHY to register with the SFP bus, so that SFP+
cages can work. This bypasses phylink, meaning that socket status
is not taken into account for the link state. Also, the tx-disable
signal must be commented out in DT for this to work...
