You later change the number of tabs for these definitions in a later
patch. Would it be better to start having the correct number of tabs?

net likes to have reverse christmas tree variables. I think you should
clean this up. However...

if (en)
val = MVPP22_FCA_ENABLE_PERIODIC;
else
val = 0;
mvpp2_modify(priv->iface_base + MVPP22_FCA_BASE(port->gop_id) +
MVPP22_FCA_CONTROL_REG, MVPP22_FCA_ENABLE_PERIODIC, val);
avoids the need for "fca".

Same reverse christmas tree issue here.
