[PATCH v4 02/23] net/cnxk: new tree for SDP interface

[Nithin Dabilpuram <ndabilpuram@marvell.com>]

From: Satha Rao <skoteshwar@marvell.com>

Create a new default tree for the SDP interface if more than one TX
queue is requested. This helps to backpressure each queue independently
when they are created with separate channels.
