Exists in smarc-l5.0.0_1.0.0-ga and in 5 other branches imx_3.10.17_1.0.1_ga, imx_3.10.53_1.1.0_ga, imx_3.14.28_1.0.0_ga, smarc-imx_3.10.53_1.1.0_ga, smarc-imx_3.14.28_1.0.0_ga

[SCSI] ipr: Increase alignment boundary of command blocks 

The latest generation of ipr hardware performs best when command blocks
are aligned to a boundary equal to the size of the command block. Ensure
512 byte alignment, since this is the largest size command block we
can send.
