crypto: caam - OP-TEE firmware support
caam driver needs to be aware of OP-TEE f/w presence, since some things
are done differently:
1. there is no access to controller's register page (note however that
some registers are aliased in job rings' register pages)
2 Due to this, MCFGR[PS] cannot be read and driver assumes
MCFGR[PS] = b'0 - engine using 32-bit address pointers.
This is in sync with the fact that:
-all i.MX SoCs currently use MCFGR[PS] = b'0
-only i.MX OP-TEE use cases don't allow access to controller register page
