c87925bfd2 crypto: inside-secure - enable single WR in DSE configuration
When enable_single_wr is not enabled, the DSE will only write those
parts of a result descriptor that need updating, which means a final
result descriptor will be written in 2 or 3 smaller transfers.
When enable_single_wr is enabled the DSE will combine these 2-3
updates into one large write transfer, generally improving performance.

39ba1bb4a4 crypto: inside-secure - fix incorrect DSE data cache setting
Set the correct value to the DSE data cache, using WR_CACHE_3BITS
instead of RD_CACHE_3BITS. This fixes an incorrect setting and helps
improving performances.

aefa794efe crypto: inside-secure - fix the ring wr_cache offset
The EIP197_HIA_xDR_CFG_WR_CACHE macro was defined to use an offset of
23, which is wrong as it's actually 25. Fix this.

1b44c5a60c crypto: inside-secure - add SafeXcel EIP197 crypto engine driver
Add support for Inside Secure SafeXcel EIP197 cryptographic engine,
which can be found on Marvell Armada 7k and 8k boards. This driver
currently implements: ecb(aes), cbc(aes), sha1, sha224, sha256 and
hmac(sah1) algorithms.

Two firmwares are needed for this engine to work. Their are mostly used
for more advanced operations than the ones supported (as of now), but we
still need them to pass the data to the internal cryptographic engine.
