Due to SPF, multiple drivers are supported and are loaded
run time. It is expected for one driver to fail to load,
however the failing driver should not flood the dmesg.
Add code to rate limit pld logs to avoid flooding of dmesg.

Deep Sleep or Hibernate are system level mode power
modes in which wlan firmware is shutdown gracefully
and linux kernel is suspended. Currently, suspend
is not allowed if firmware is down, with this change
suspend is allowed if firmware is down due to Deep
Sleep or Hibernate low power state.
A new pld api is introduced to know the low power
state from platform driver, this api is enabled based
on CONFIG_ENABLE_LOW_POWER_MODE flag. Currently, this
feature is enabled only for wearable targets.

Currently sched-delay is not taken into account while calculating TX/RX
offload packets in bus bandwidth work handler. This may result in an
incorrect calculation and determination of TX/RX bandwidth levels and
other params which are derived from it.
Add support to consider actual scheduling delay between two bandwidth
intervals to detemine TX/RX offloaded/not-offloaded packets.

Set system PM_QOS with low latency only for "very-high" throughput levels

In less than "very-high" throughput cases, this allows CPU cores to
enter low power modes. This is done only for non-offloaded packets e.g.
UDP.

For this feature, it need to power down wlan chip when
suspend, and power up wlan chip when resume, so need to

wlan chip instead of calling wlan driver suspend when do
suspend, and changing to do power on wlan chip, download
wlan firmware, and calling wlan driver reinit instead of
calling wlan driver resume when do resume.
