Bug description:
  ======================= Firmware ================

  [Impact]
  The new device needs a new firmware, rtw89/rtw8852bt_fw.bin.

  [Fix]
  Clear cherry picked the following commit from linux-firmware
  0a69dcd3 rtw89: 8852bt: update fw to v0.29.122.0 and BB parameter to 07
  882976ea rtw89: 8852bt: update fw to v0.29.110.0
  bb88fb74 rtw89: 8852bt: add firmware 0.29.91.0

  [Test]
  1. Boot up a system that comes with Realtek wifi device[10ec:b520]
  2. Check if the realtek wifi works

  [Where problems could occur]
  Adding one new firmware for the new device, there should be no regression.

  ======================= Kernel ================

  [Impact]
  The new Realtek wifi device[10ec:b520] requires a new driver to support

  [Fix]
  This series of patch is required which are included in v6.12-rc1

  2. Check if the driver rtw89_8852bte is loaded

  [Where problem could occur]
  This is adding new driver, so should have minimal impact on the existing 
systems.
