locking: Introduce prepare_sync_core_cmd()
Introduce an architecture function that architectures can use to set
up ("prepare") SYNC_CORE commands.
The function will be used by RISC-V to update its "deferred icache-
flush" data structures (icache_stale_mask).
Architectures defining prepare_sync_core_cmd() static inline need to
select ARCH_HAS_PREPARE_SYNC_CORE_CMD.
