The zephyr documentation says k_poll to operate on objects - kernel
fifo, poll signal, semaphore. Can't it also be used on mailboxes,
message queues etc?
Looking at the include/kernel.h, all k_poll'able object must have
a .poll_events member (either directly or via _POLL_EVENT macro).
Mailboxes and message queues don't have it. This can be confirmed by
looking at kernel/poll.c:register_event(), which handles each of the
supported pollable objects via a switch statement.
