Initialize the ssf_client earlier during the boot process during post kernel. ssf_client needs to be initialized before the CONFIG_NRF_802154_SER_RADIO_INIT_PRIO since it is used by the "nRF IEEE 802.15.4" protocol. It also needs to be initialied after the IPC IPC_SERVICE_REG_BACKEND_PRIORITY since the IPC expects the protocol to be initialized. Failing to do that will also trigger an assertion in Zephyr. Signed-off-by: Georgios Vasilakis <[email protected]>
There are two functions which are defined in the psa_crypto_core.h and are implemented in psa_crypto.c which are used by the TLS library. These functions are: psa_can_do_hash psa_can_do_cipher These functions just check if the drivers are initialized before the relevant PSA crypto functions can be used. In the case of SSF there is no initialization needed because the PSA initialization happens inside the secure domain firmware before the application boots. These functions are added in a separate file since they only exist to maintain compatibility with the PSA core from Oberon/mbedTLS and they don't need to forward any call to the secure domain.

The commits are identical apart from some formatting in the commit which adds PSA compatibility layer for SSF.
This mainly fixes an initialization issue with the nRF IEEE 802.15.4 and IPC, please check the commits messages.
