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.

As per Hibernate Entry (i.e. SUBSYS_BEFORE_SHUTDOWN with flag
crashed is not set) and based on low power supports it set the
state to ICNSS_LOW_POWER.
While processing the SUBSYS_AFTER_SHUTDOWN, its reset the
ICNSS_LOW_POWER state based on previous state already set
state and low power supported.
But before system freeze callback triggered,
SUBSYS_AFTER_SHUTDOWN event received to wlan and due to
which ICNSS_LOW_POWER state is clear and freeze callback failed,
thus its leads to prevent Hibernate freeze on WLAN.
This fix is to provides WLAN entered into Hibernate freeze state
by not clearing ICNSS_LOW_POWER state in SUBSYS_AFTER_SHUTDOWN.

Hibernate is a system wide power mode during which Modem
would be brought down along with DDR and the RAM contents
would be saved on the disk (suspend-to-Disk).
Modem would be do graceful shutdown in Hibernate mode,
so BEFORE_SUBSYS_DOWN notification will be received.
Based on dtsi node "is_low_power", if BEFORE_SUBSYS_DOWN
with notif->crashed bit not set is received, platform
driver will trigger an idle shutdown and set low power mode.
On AFTER_SUBSYS_DOWN notification, low power mode will be
cleared if it was set and ramdump collection will happen
only in case of crash.

Deep Sleep is a system wide low power mode during which
Modem would be brought down and DDR would be in self
refresh mode (suspend-to-RAM) thus platform driver on
receiving deep sleep indication goes to a state similar
to SSR apart from the fact that FW is not crashed but
deliberately brought down.
In msm-5.15, there are no seperate notifications used
for deep sleep, notifications used for hibernate like
BEFORE_SHUTDOWN, AFTER_SHUTDOWN, BEFORE_POWERUP and
AFTER_POWERUP are used for deep sleep also.
In this commit add only low power mode state to
