I am seeing compilation errors like:

In file included from drivers/crypto/caam/ctrl.c:25:0:
drivers/crypto/caam/qi.h:87:6: error: variably modified 'sh_desc' at file scope
  u32 sh_desc[MAX_SDLEN];
      ^

Adding comments for this commit, since it looks like the fixes
should be included here (related to DESC_JOB_IO_LEN vs. DESC_JOB_IO_LEN_MAX).

Please make sure caam/qi and and caam/qi2 drivers are at least compile-tested.

By caam/qi I am referring to:
CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI=y/m

and caam/qi2:
CONFIG_CRYPTO_DEV_FSL_DPAA2_CAAM=y/m
