Subject: [patch net-next 08/18] mlxsw: spectrum_buffers: Remove eg pool 3 default init and CPU port TC binding to it

From: Jiri Pirko <jiri@...lanox.com>

Since there is no congestion control for CPU port traffic, we can change
the CPU port TC binding to pool 0 with min_buff and max_buff zeroed.
Remove initialization for pool egress pool 3 since it is no longer used
by dafault.
