dts: stm32: add SAES dependency on RNG firewall configuration for stm32mp13

SAES is connected to RNG by an internal RNG bus to be DPA resistant.
We must ensure that RNG is allocated to the secure world to prevent
the non secure to shut down the RNG peripheral.
Therefore add RNG to the access-controllers of SAES node in stm32mp13
SoC DTSI files.

core: arm: ffa: switch to FF-A version 1.2

Update FF-A minor version from 1 to 2. spmc_exchange_version() is

Configurations with SPMC at EL3 and S-EL2 supplies an SP manifest when
booting OP-TEE, read the FF-A version to use from the manifest instead
of using the hard coded version.

The configuration with SPMC at S-EL1, part of OP-TEE, keep the FF-A
version at version 1.1 when configured with CFG_NS_VIRTUALIZATION=y as
workaround to remain compatible with Xen. This workaround will not be
needed after the next Xen release and can be removed then.

core: arm: ffa: use SMC Calling Convention 1.2

Add struct thread_smc_1_2_regs as a replacement for struct
thread_smc_args when dealing with FF-A SMCs. struct thread_smc_1_2_regs
covers the registers x0-x17 to support passing arguments and results
according to SMC Calling Convention (SMCCC) version 1.2.

The difference is that before this change x8-x17 couldn't be used as
argument nor result and the content was preserved. With this patch are
x8-x17 returned as zeroes. New FF-A SMCs can take and return values in
the full range x0-x17.

64-bit SMCCC version 1.1 and earlier specified x4-x17 as unpredictable
or scratch registers. FF-A has specified x0-x7 as argument and result
registers, regardless of SMCCC. This has changed with SMCCC version 1.2
where the two standards harmonize on this.

struct thread_smc_1_2_regs is added in a 32-bit version for
compatibility, but it only covers r0-r7.
