[PATCH v2] drivers: remove support to limit XAQ in cnxk event driver

[Shijith Thotton <sthotton@marvell.com>]

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

v2:
 * Removed used function parameter.

   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]
