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.

Add support to configure log level for dmesg and
ipc logging. Default log level is set to DEBUG
for ipc logging and INFO for dmesg logging.
Change default behavior of cnss_pr_dbg and
cnss_pr_vdbg API to not print in dmesg.

MHI INIT called during host driver registration leads to MHI state
mismatch because MHI is already in INIT state due to power up of
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.

Cnss2 driver receives cnss_pci_smmu_fault_handler cb from smmu
driver whenever wlan fw access illegal IOVA address. In
cnss smmmu fault cb handler, cnss2 driver rings trace stop
door bell register to stop tracing in wlan fw. This will
help to get proper traces to debug where illegal access
is happening in wlan fw.

on some auto platform, host need explicitly tell firmware

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.

Add new "qcom,no-bwscale" under child device node to
indicate it want to disable bw scalling.
And the background is like HSP, it has stability issue
with some specific pcie cable with gen3, so it will
negotiate with RC side to change from gen3 to gen2
with MHI_ER_BW_SCALE_ELEMENT_TYPE event, which will
impact all the platform that want to keep use gen3.
So add this device tree config item to skip the link
speed negotiation.

Currently, cnss_do_host_ramdump() is allocating memory for a new segment
to be added to list to be written to ramdump, but it is not accounting
for the case that the kcalloc call returns NULL for the segment pointer.
Thus, add a null check after memory is allocated for the segment.
