event/cnxk: remove option to limit XAQ

Browse Source 
Removed support to limit XAQ from devargs. If XAQ is limited, new add
works could run out of XAQ entries and disable the queue.

We can control the QoS of SSO GGRP by modifying the above mentioned
thresholds. GGRPs that have higher importance can be assigned higher
thresholds than the rest. The dictionary format is as follows
[Qx-XAQ-TAQ-IAQ][Qz-XAQ-TAQ-IAQ] expressed in percentages, 0 represents
default.
[Qx-TAQ-IAQ][Qz-TAQ-IAQ] expressed in percentages, 0 represents default.
For example::
-a 0002:0e:00.0,qos=[1-50-50-50]
-a 0002:0e:00.0,qos=[1-50-50]
