net/bnxt: cleanup ULP parser and mapper

1. Disable accum_stats for Thor
2. Delete the generic port table for default flow
3. The packet mask to calculate the number of packets must be 28 bits.
4. Increase the WC TCAM entries to 512 per application and add 2
shared L2 context TCAM entries to match identifiers for flow
scaling
5. Ignore multiple critical resources in ULP flow database
6. Renamed conditional code update to function opcode.
7. Updated TRUFLOW debug logs to support the above changes.
8. As part of the HA cleanup, the shared session name now allows the user
to designate that the session uses the wc_tcam regions within the
shared session.
9. The CFA action pointer does not exist if there is no support for
VF representor, so no need to display the message for use case where
there is no support for VF representors.
10. Cleanup flow counter software accumulation.
11. When an application exits ungracefully, the HA code now
clears the appropriate shared WC region and sets the HA state.
12. Removal of unnecessary INFO message. The message is an indicator that
the ports are being removed from DPDK, but all cleanup has not
completed. Once the cleanup is completed, the timer will be stopped.

net/bnxt: refactor flow parser in ULP

1. Remove Ether type, VLAN type and IP proto type from pattern matching,
since the header bits can be used for matching. This reduces the class
template signatures by a factor of 8.

2. Remove the wild card bit in the pattern matching since same template
can be used for both exact and wild card entries.

3. The action record pointers have to use higher range to not collide
with the firmware action record pointers. Hence reduced the number of
action record pointers for Whitney platform.

4. The conditional update opcode provide functionality to reject flows
for instance reject flows that do not adhere to flow signature match.

5. Added check to not populate protocol specifications if the
protocol mask is null or zero.

6. Check that field array is not overrun.

Unify the opcodes of the different enums into a single enum for reuse of
common processors. Also the ADD_PAD opcode is now SET_TO_ZERO.
This change better reflects the intent of the opcode and allows it to be
used in more circumstances without overloading the term pad.
The fields that were setting a constant zero have now been switched to
use the new SET_TO_ZERO opcode as an optimization. The SET_TO_ZERO does
not copy data into the key/result/mask fields, but rather simply
increments the write pointer.

Currently, all the flow templates are sequentially searched to find out
whether there is a matching template for the incoming RTE_FLOW offload
request. As sequential search will have performance concerns, this
patch will address it by using hash algorithm to find out the flow
template. This change resulted in creation of computed fields to
remove the fields that do not participate in the hash calculations.
The field bitmap is created for this purpose.
