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. v5 changes: 1. Minor changes in coding style. 2. Added DMA_CTRL_ACK flag initialization v4 changes: 1. Fixed dma-ranges property on DTS.
