MLK-9769-20 Limit AXI pipeline to a depth of one in CAAM for i.MX6 devices

i.MX6 devices have an issue wherein AXI bus transactions may not occur
in the correct order. This isn't a problem running single descriptors,
but can be if running multiple concurrent descriptors. Reworking the CAAM
driver to throttle to single requests is impractical, so this patch limits
the AXI pipeline to a depth of one (from a default of four) to preclude
this situation from occurring.
