drivers: crypto: stm32: add an error trace when registering CRYP and SAES

Drvcrypt framework can only register one symmetric cipher driver.
Add an explicit error trace in function stm32_register_cipher() when
several cipher drivers are registered.

drivers: crypto: remove assertions on device handlers

Remove assertions added by the commit referred below. They are useless
since the handlers are registered only if the related device (stm32_cryp
or stm32_saes) has its driver successfully probed. These assertion also
prevent enabling both CFG_STM32_SAES and CFG_STM32_CRYP for a platform
which is a valid configuration for when we rely on the DT to state
which of both is enabled.

drivers: crypto: stm32_saes: fallback to software on 192bit AES keys

Implement AES software operation for 192 bits keys as these are not
supported by the STM32 SAES peripheral. For that purpose ciphering final,
context copy and context freeing operations common functions are split
into CRYP/SAES peripheral specific functions.

Move cipher context allocation and free functions to place them
next to each other for CRYP and SAES support to ease their maintenance
