raid5 xor and raid6 p+q.

v8 changes:
	1. Fixed macro namespace issues.
	2. Fixed tx status check issues.
v7 changes:
	1. Added raid5 xor offload support.
	2. Added raid6 p+q offload support.
v6 changes:
	1. Maintained sw queue for pending, running, and completed
	   requests. Used link list as queue.
	2. Fixed issue_pending and tx_submit routines.
	3. Fixed prep_dma routines.
	4. Fixed free_irqs.
