octeontx2-pf: Add support for page pool

Page pool for each rx queue enhance rx side performance
by reclaiming buffers back to each queue specific pool. DMA
mapping is done only for first allocation of buffers.
As subsequent buffers allocation avoid DMA mapping,
it results in performance improvement.

octeontx2-pf: Add support for HTB offload

This patch registers callbacks to support HTB offload.

Below are features supported,

- supports traffic shaping on the given class by honoring rate and ceil
configuration.

- supports traffic scheduling, which prioritizes different types of

octeontx2-pf: qos send queues management

Current implementation is such that the number of Send queues (SQs)
are decided on the device probe which is equal to the number of online
cpus. These SQs are allocated and deallocated in interface open and c
lose calls respectively.

This patch defines new APIs for initializing and deinitializing Send
queues dynamically and allocates more number of transmit queues for
QOS feature.
