apm821xx: backport and reassign crypto4xx patches

This patch backports several patches that went upstream into
Herbert Xu's cryptodev-2.6 tree:

crypto: Use zeroing memory allocator instead of allocator/memset
crypto: crypto4xx - performance optimizations
crypto: crypto4xx - convert to skcipher
crypto: crypto4xx - avoid VLA use
crypto: crypto4xx - add aes-ctr support
crypto: crypto4xx - properly set IV after de- and encrypt
crypto: crypto4xx - extend aead fallback checks
crypto: crypto4xx - put temporary dst sg into request ctx

The older, outstanding patches from 120-wxyz series have been
upstreamed as well and therefore they have been reassigned to
fit into the series.

-Subject: [PATCH 1/6] crypto: crypto4xx - shuffle iomap in front of request_irq
-
-It is possible to avoid the ce_base null pointer check in the
-drivers' interrupt handler routine "crypto4xx_ce_interrupt_handler()"
-by simply doing the iomap in front of the IRQ registration.
-
-This way, the ce_base will always be valid in the handler and
-a branch in an critical path can be avoided.
