driver: caam: disable RNG buffering

Previous design of keeping RNG data in a buffer and giving random number
to user from that buffer is vulnerable to attacks and also not NIST/FIPS
compliant.
So to make it more secure and NIST/FIPS compliant, will get random
number from CAAM on each user request.

drivers: stm32_gpio: update and fix RIF configuration handling

The conditions to acquire or release RIF semaphores when applying
the CID filtering configuration were incorrect. Add
handle_available_semaphores() to handle correctly the RIF semaphores.
Also remove FMC_NB_MAX_CID_SUPPORTED and use generic MAX_CID_SUPPORTED.

Also add a dummy apply_rif_config() when CFG_STM32_RIF is not defined.

Fix unfreed banks when they are removed from the bank list.

drivers: stm32_hsem: fix HSEM group CID filtering configuration

Move the check on HSEM group CID filtering configuration consistency
before the continuing if the CID filtering is disabled for the first
semaphore of the group.

The HSEM group CID filtering was also broken as it didn't allow more
than one CID to access a semaphore group. Fix this by using the semaphore
bit-field in the RIFPROT macro to determine what are the processors that
should be authorized to take the semaphores.
