mailbox: imx: Move the RX part of the mailbox into the threaded handler

Move RX callback handling into the threaded handler. This is similar to
the TX side except that we explicitly mask the source interrupt in the
primary handler and unmask it in the threaded handler again after
success. This was done automatically in the TX part.

The masking/ unmasking can be removed from imx_mu_specific_rx() since it
already happens in the primary/ threaded handler before invoking the
channel specific callback.

Move RX channel handling into threaded handler.
