octeontx2-af: NIX Tx scheduler queue config support

This patch adds support for a PF/VF driver to configure
NIX transmit scheduler queues via mbox. Since PF/VF doesn't
know the absolute HW index of the NIXLF attached to it, AF
traps the register config and overwrites with the correct
NIXLF index.

HW supports shaping, colouring and policing of packets with
these multilevel traffic scheduler queues. Instead of
introducing different mbox message formats for different
configurations and making both AF & PF/VF driver implementation
cumbersome, access to the scheduler queue's CSRs is provided
via mbox. AF checks whether the sender PF/VF has the
corresponding queue allocated or not and dumps the config
to HW. With a single mbox msg 20 registers can be configured.

octeontx2-af: NIX Tx scheduler queues alloc/free

Added support for a PF/VF to allocate or free NIX transmit
scheduler queues via mbox. For setting up pkt transmission
priorities between queues, the scheduler queues have to be
contiguous w.r.t their HW indices. So both contiguous and
non-contiguous allocations are supported.

Upon receiving NIX_TXSCH_FREE mbox msg all scheduler queues
allocated to sending PFFUNC (PF/VF) will be freed. Selective
free is not supported.

octeontx2-af: Support for disabling NIX RQ/SQ/CQ contexts

This patch adds support for a RVU PF/VF to disable all RQ/SQ/CQ
contexts of a NIX LF via mbox. This will be used by PF/VF drivers
upon teardown or while freeing up HW resources.

A HW context which is not INIT'ed cannot be modified and a
RVU PF/VF driver may or may not INIT all the RQ/SQ/CQ contexts.
So a bitmap is introduced to keep track of enabled NIX RQ/SQ/CQ
contexts, so that only enabled hw contexts are disabled upon LF
teardown.

These formats tell HW which fields in the TCP packet's

offload.

Also report PF/VF drivers the LSO format indices as part
of response to NIX_LF_ALLOC mbox msg. These indices are
used in SQE extension headers while framing SQE for pkt
transmission with TSO offload.
