aa2faec1a0 crypto: caam - Moved macro DESC_JOB_IO_LEN to desc_constr.h
DESC_JOB_IO_LEN is a generic macro which indicates the space required in
the descriptor for placing SEQIN/OUT commands, job descriptor header,
shared descriptor pointer. Moving it to descriptor construction file
which can be supposedly included by different algo offload files.

61bb86bba1 crypto: caam - set descriptor sharing type to SERIAL
SHARE_WAIT, whilst more optimal for association-less crypto,
has the ability to start thrashing the CCB descriptor/key
caches, given high levels of traffic across multiple security
associations (and thus keys).

Switch to using the SERIAL sharing type, which prefers
the last used CCB for the SA.  On a 2-DECO platform
such as the P3041, this can improve performance by
about 3.7%.

95bcaa3905 crypto: caam - add backward compatible string sec4.0
In some device trees of previous version, there were string "fsl,sec4.0".
To be backward compatible with device trees, we first check "fsl,sec-v4.0",
if it fails, then check for "fsl,sec4.0".
