  [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.

  [Where problems could occur]

  This MR comes from upstream commit, 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.
