Bug Description
This is SRU template for linux kernel:
[Impact]
On a Dell laptop, let it connect to a WiFi router, connect a BT
device, then disconnect it, connect the bt device again, we expect
the device could be connected successfully, but it couldn't and
the BT firmeware crashed.
[Fix]
Need to upgrade the firmware for RTL8852CE and cherry-pick 2 kernel
patches, here we send the MR for 2 kernel patches. The firmware PR was
already sent out. And one of the patches is from linux-next, the other is
from rtw.git and is going to be merged to linux-next soon.
[Test Case]
With the upgraded firmware + kernel with the 2 kernel patches, bt
firmware will not crash anymore and bt could connect / disconnect
many many bt devices.
[Where problems could occur]
This MR comes from upstream commits, it has low possibility to
introduce regression. If the bt or wifi on this laptop couldn't
work as well as before, it is possible that this MR introduces
regression. According to our test, the wifi and bt could work well
with upgraded firmware.

[Impact]
On a Dell laptop, let it connect to a WiFi router, connect a BT
device, then disconnect it, connect the bt device again, we expect
the device could be connected successfully, but it couldn't and
the BT firmeware crashed.
[Fix]
Need to upgrade the firmware for RTL8852CE and cherry-pick 2 kernel
patches, here we send the MR for firmware first. And it is backward
compatible, the upgraded firmware could work with kernel without
those 2 patches as well as before.
[Test Case]
With the upgraded firmware + kernel without the 2 kernel patches,
the wifi and bt could work as well / bad as before.
With the upgraded firmware + kernel with the 2 kernel patches, bt
firmware will not crash anymore and bt could connect / disconnect
many many bt devices.
