Fix missing cast when saving pre-computed masks in STM32 SAES driver

The issue is revealed by xtest regression_4017 when run with at least

Fix missing cast when saving pre-computed masks in STM32 CRYP driver
CTR implementation when several small input data is provided to

The issue could be found, for example, by assigning STM32 CRYP to OP-TEE
in stm32mp1-157C_DK2 board DTS file (patch below) and running xtest
regression_4017 with level 15 ("xtest -l 15 regression_4017").

Example of a patch on stm32mp157c-dk2.dts file to use CRYP driver for

Issues in the ELE FW have been found when both, secure and

To prevent any issue, rely on RNG software in OPTEE. The compilation of
hw_get_random_bytes() is conditioned by CFG_WITH_SOFTWARE_PRNG.
Set CFG_WITH_SOFTWARE_PRNG=y by default.

With CFG_WITH_SOFTWARE_PRNG enabled in OP-TEE, ELE will not be used
in OP-TEE at runtime and Linux can access the ELE without conflicts.

drivers: ele: enable TRUST MU in OP-TEE for i.MX93-EVK/i.MX91-EVK

There is TRUST MU available on i.MX91 and i.MX93 platforms.

TRUST MU can be used to access some HW features of Edgelock Enclave which
Normal MU cannot, but for now it is configured to be used to communicate
with ELE FW.

So Kernel will use Normal MU and OP-TEE will use TRUST MU.

There is special setup needed to write to Trust MU.
* First for TRUST-MU we must write a valid command to TR0 before we can
write any of the remaining registers, and TR15 is reserved for special
USM command.
* The CMD field for TR0 is bits 31:26 and must be greater than
the value of the watermark set in SCM_CR2[31:22]. Typically
if you just set the MSB (bit 31) its enough.
* SIZE must be programmed in bits 19:16 of TR0, we cannot write
TRn past the specified size in this bit field
