[PATCH v5 01/28] common/cnxk: add multi channel support for SDP send queues

[Nithin Dabilpuram]

From: Subrahmanyam Nilla <snilla at marvell.com>

Currently only base channel number is configured as default
channel for all the SDP send queues. Due to this, packets
sent on different SQ's are landing on the same output queue
on the host. Channel number in the send queue should be
configured according to the number of queues assigned to the
SDP PF or VF device.
