SRU Justification
=================

[Impact]
Less beacons were found in BLE scanning with RS9113 chipset.

[Fix]
BLE Scanning is happening for less scan window, which is causing this issue. Scan window value is adjusted (increase)dynamically in firmware when there is no activity on WiFi/BT. Along with this fix i firmware, we have added deep sleep feature in driver. Driver will put chip in sleep state when there is not activity.

[Test Case]
Conducted tests to confirm BLE scanning results are improved with the driver and firmware changes. Also, ran suspend resume s3, s4 and s5 stress tests to ensure it passed with newly added sleep changes
