bool "Use a semaphore when waiting for completions in rtio_submit"

help
When calling rtio_submit a semaphore is available to sleep the calling
thread for each completion queue event until the wait count is met. This
adds a small RAM overhead for a single semaphore. By default wait_for will
use polling on the completion queue with a k_yield() in between iterations.
Enabled by default unless !MULTITHREADING

When calling rtio_cqe_consume_block a semaphore is available to sleep the
calling thread for each completion queue event until the wait count is met.
This adds a small RAM overhead for a single semaphore. By default the call
will use polling on the completion queue with a k_yield() in between

help
Enable the RTIO_DEFINE_WITH_MEMPOOL macro which allows queueing reads
without a pre-allocated memory buffer. Instead the buffer will be taken
from the allocated memory pool associated with the RTIO context.
