slim_disable_stream() and slim_stream_unprepare() are exported, so add
sanity checks preventing unmatched/invalid calls.

Correct few frequencies in presence rate table - multiplied by 10
(110250 instead of 11025 Hz).

The kerneldoc comments in drivers/slimbus/stream.c were not properly
formatted, leading to a distinctly unsatisfying "no structured comments
found" warning in the docs build. Sprinkle some asterisks around so that
the comments will be properly recognized.

This patch adds support to SLIMbus stream apis for slimbus device.
SLIMbus streaming involves adding support to Data Channel Management and
channel Reconfiguration Messages to slim core plus few stream apis.
>From slim device side the apis are very simple mostly inline with other
stream apis.
Currently it only supports Isochronous and Push/Pull transport protocols,
which are sufficient for audio use cases.
