Makes sure that normal world cannot change the size of allocated shared
memory, resulting in a smaller buffer being allocated.
This reintroduces cc6bc5f94210 ("core: verify size of allocated shared
memory") which was lost with Fixes: 2786f1438fc8 ("core: thread:
separate old SMC interface handling"). In addition is the READ_ONCE()
macro is used when reading the returned size from non-secure shared
memory.
Since then we have a separate set of functions to deal with RPC when
communicating with FF-A. A corresponding size check is added for the
FF-A version of thread_rpc_alloc().
