fm10k: allocate logical ports for flow director

Browse Source 
In fm10k, PF, VF, VMDQ or queues binding to flow director rule can
be considered as a logical port. Original implementation only creates
a single port for all cases. This change creates 128 logical ports;
first 64 for PF and VMDQ, second 64 for flow director.

Registers DGLORTDEC/DGLORTMAP define rules for how to classify packets
into different queues. Currently only PF and VMDQ cases are considered.
This change add rules for flow director.
