crypto: caam/qi - optimize frame queue cleanup

Add reference counter incremented for each frame enqueued in CAAM
and replace unconditional sleep in empty_caam_fq() with polling the
reference counter.

When CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y boot time on LS1043A
platform with this optimization decreases from ~1100s to ~11s.
