fix(drivers/scmi-msg): smt: fix build for aarch64

For AARCH64, BIT() will make the number as ULL type, let use BIT_32()
here.

And use %zu for size_t print format.

drivers/scmi-msg: smt entry points for incoming messages

This change implements SCMI channels for reading a SCMI message from a
shared memory and call the SCMI message drivers to route the message
to the target platform services.

SMT refers to the shared memory management protocol which is used
to get/put message/response in shared memory. SMT is a 28byte header
stating shared memory state and exchanged protocol data.

The processing entry for a SCMI message can be a secure interrupt
or fastcall SMCCC invocation.

SMT description in this implementation is based on the OP-TEE
project [1] itself based in the SCP-firmware implementation [2].
