octeontx2-af: Restrict TL1 allocation and configuration

TL1 is the root node in the scheduling hierarchy and
it is a global resource with a limited number.

This patch introduces restriction and validation on
the allocation of the TL1 nodes for the effective resource
sharing across the AF consumers.

- Limit TL1 allocation to 2 per lmac.
One could be for the normal link and one for IEEE802.3br
express link (Express Send DMA).
Effectively all the VF's of an RVU PF(lmac) share the two TL1 schqs.
- TL1 cannot be freed once allocated.
- Allow VF's to only apply default config to TL1 if not
already applied. PF's can always overwrite the TL1 config.
- Consider NIX_AQ_INSTOP_WRITE while validating txschq
when sq.ena is set.

octeontx2-af: Add support for runtime RSS algo index reservation

Introduced reserve_flowkey_alg_idx()to reserve RSS algorithm index,
it would internally use set_flowkey_fields() to generate fields
based on the flow key dynamically.

On AF driver init, it would reserve a predefined set RSS algo indexes,
which will be available all the time for all the AF driver consumers.
The leftover algo indexes can be reserved at runtime through
exiting nix_rss_flowkey_cfg mailbox message.

The NIX_FLOW_KEY_TYPE_PORT is removed from predefined a set of RSS flow
type as it is not used by any consumer.

octeontx2-af: Add support for dynamic flow cfg to RSS field generation

Introduce state-based algorithm to convert the flow_key value

The outer `for loop` goes over _all_ protocol field and the following
variables depict the state machine forward progress logic.

a) keyoff_marker - Enabled when hash byte length needs to be accounted
in field->key_offset update.
b) field_marker - Enabled when a new field needs to be selected.
c) group_member - Enabled when a protocol is part of a group.

This would remove the existing hard coding and enable to add
new protocol support seamlessly.
