qed: Update FW init functions to support FW 8.59.1.0

The qed_init_fw_func.c and qed_init_ops.c updated to support FW
version 8.59.1.0.
  - Support 16-bit VPORT WFQ (weighted fair queueing) weights.
  - Support WFQ (weighted fair queueing) weight per VPORT + TC.
  - Support allocation of Tx PQs(physical queues) per PF,VF.
  - Modify Global RL (rate limiter) upper bound configuration.
  - Update FW operation functions.
  - Update iro_arr[] array.

This patch also fixes the existing checkpatch warnings and few important
checks.
