net: ethernet: am65-cpsw: Set default TX channels to maximum 



am65-cpsw supports 8 TX hardware queues. Set this as default.

The rationale is that some am65-cpsw devices can have up to 4 ethernet
ports. If the number of TX channels have to be changed then all
interfaces have to be brought down and up as the old default of 1
TX channel is too restrictive for any mqprio/taprio usage.

Another reason for this change is to allow testing using
kselftest:net/forwarding:ethtool_mm.sh out of the box.
