Add cnss_update_time_sync_period and cnss_reset_time_sync_period to
update time sync period vote sent from wlan driver based on use-case.
CNSS driver stores both wlan driver and sys config time sync period
value and will apply the minimum value of all votes.

There is scenario where cnss-daemon is got connected with
cnss-plat-ipc module but message to initialize daemon
config is not yet received from cnss-daemon. At the same
time cnss2 module checks for DMS support in daemon config
which is not yet initialized. As use-nv-mac is set from DTSI,
DMS support must be enabled. Since it is not found enabled,
cnss2 asserts.
To fix this, along with cnss-daemon connection check also
wait for message from cnss-daemon which initializes daemon
config.

Host triggered force assert can be called asynchronous.
As part of force assert, CNSS dumps few MHI registers and
trigger RDDM asynchronously. There are chances of race between
force assert and runtime suspend.
To fix that take runtime get reference before MHI operations and
runtime put later.

During cold boot AON sends multiple DOWN and UP notifications
as part of its FW update. ICNSS driver should not initiate
any QMI handshakes and should wait till correct FW is flashed.
After successfully flashing correct FW, AON will send ready event.
Once AON ready event receives ICNSS driver sets AON ready bit and
proceeds with QMI handshakes.
Similarly in AON SSR, this change handles UP notification only if
AON ready bit is set.

Some platform PCIe RC impedance can't achieve the target defined in spec.
It will result to Genoa card link down. To WA the issue, downgrade RC speed
to Gen1 for auto Genoa EP. Because the linkdown issue may happen during
enum, and before enumunation we do not know EP device ID, so set init
speed to Gen1, and then restore speed to default for others wifi chip.
The change does not affect Genoa throughput, because Gen1 speed is enough
for Genoa.

Commit 97303bf330 ("cnss_prealloc: update prealloc mem pool based on
device type") introduced several new dependencies:
- cnss_prealloc has a dependency upon a new header file
cnss_utils/cnss_common.h
- cnss2 has a dependency upon cnss_prealloc
- icnss2 has a dependency upon cnss_prealloc
- icnss2 has dependency upon cnss_utils and wlan_firmware_service
Add those dependencies to the DDK build rules.
Also add CNSS_OUT_OF_TREE config in icnss2/Kconfig file.

MHI INIT called during host driver registration leads to MHI state

device as part of ongoing self recovery.
To fix this issue, avoid powering up device during recovery if host
driver is not registered. Device would be powered up later during
host driver registration.

CNSS prealloc maintains various prealloc pools of 8Kb, 16Kb, 32Kb
and so on, and allocates buffer from the pool for wlan driver. When
wlan driver requests to free the memory buffer then CNSS prealloc
needs to first find out mempool id from which this buffer was allocated.
Use slab_cache from slab struct to identify memory pool id. Until
kernel 5.16, slab_cache was part of page struct but in kernel 5.17,
slab_cache is moved out to mm/slab.h file.
Also change WCNSS_PRE_ALLOC_GET_THRESHOLD to 8Kb to match with
cnss_pool_alloc_threshold.
