Add support for 8.14.x.x firmware.

The new firmware adds support for external PHY BCM8485x; configures
fixed link speed with transceiver/cable not supporting negotiation;
supports engine swap; supports overriding PCIe preset equalization
value; checks pause too long for ports and reads die temperature
every second for shutdown threshold.
It includes change in FLR flow when there is a SW initiated FLR.

net/nfp: avoid modulo operations for handling ring wrapping

Having those modulo operations implies costly instructions execution,
what can be avoided with conditionals and unlikely clauses.

This change makes the software ring read and write indexes to be now
always within the ring size which has to be handled properly. The main
problem is when write pointer wraps and being less than the read pointer.
This happened before, but just with indexes type size (uint32_t) wrapping,
and in that case the processor does the right thing no requiring special
handling by software.

This work has also led to discovering redundant pointers in the driver,
which have been removed.
