[PATCH] firmware: ti_sci: replace kcalloc with kzalloc for buffer pointer allocation

Previously, the buffer pointer was being allocated via devm_kcalloc that
would check for a mul overflow before allocating n * size bytes
(size being desc->max_msg_size), but since n is 1 here, we can instead
use devm_kzalloc that allocates the size directly.
