To prevent too many bufferred message from flushing out to serial when
we turn on/off display and blocking other high priority task due to
disabled IRQ, we change some prints to debug level to workaround that
problem as a short-term solution. The long-term will be implemented
later.

This change corrects the logic for tracking stats syncpoint
threshold.
In UMD, IspNg sets flag stats_aidx_flag per stats block enabled.
In RCE, this is copied over to the task descriptor as
stats_action_mask.
In Falcon, this mask is used to determine how many times the
stats syncpoint shall be incremented.
This change fixes the logic in isp_capture_request to have the
threshold be based on the same flag from IspNg, by reading it
from the program buffer.

- Therefore instead of having a common name for all OSs for this

- Similary rename dce_os_device struct to dce_linux_device and

- I2b8a24f9044bc08e10e5ff8cbf0c3f51fa53ff53 change introduced
an issue of concurrent accesses of admin message buffer
by different admin channel clients.
- This change will fix this issue by adding set of buffers per admin
channel client.
- When a admin channel client wants to use a buffer it will
have to request using it's client ID.
Buffer will be granted only if at least one buffer for that client
is not in use.
- Admin channel clients must release the buffer once done with the
usage so that it's available for other accesses by the same client.
- Do we need a mutex to protect this array?
1) There's no issue if different clients are trying to get/put
buffers concurrently since each query will operate on
separate per client array.
2) We've an assumption that none of the clients will be active
during init. This is also documented as part of function
documentation.
3) Will we ever have a usecase where a same client does
get/put concurrently?
4) Is it possible for a client to be active during de-init?
- If answer to 3 or 4 is yes then we still need a mutex to protect
the buffers.
- Currently we've assumed that there woudn't be concurrent
operations during init/deinit and on same client so
we're not introducing any mutex.
