[Impact]

Some OEM design RTK-8852c as WiFi/BT solution on new platform, need to add
both FW & config file to get it work with oem-6.0.

WiFi: rtw8852c

  rtw89_8852ce 0000:02:00.0: enabling device (0000 -> 0003)
  rtw89_8852ce 0000:02:00.0: Direct firmware load for rtw89/rtw8852c_fw.bin failed with error -2
  rtw89_8852ce 0000:02:00.0: failed to request firmware
  rtw89_8852ce 0000:02:00.0: failed to wait firmware completion
  rtw89_8852ce 0000:02:00.0: failed to setup chip information
  rtw89_8852ce: probe of 0000:02:00.0 failed with error -22

BT: rtl8852cu

  Bluetooth: hci0: RTL: loading rtl_bt/rtl8852cu_fw.bin
  Bluetooth: hci0: RTL: firmware file rtl_bt/rtl8852cu_fw.bin not found

[Fix]

rtw89/rtw8852c_fw.bin and rtl_bt/rtl8852cu_fw.bin are required. Kinetic
has already 5 commits out of 8.

[Test Case]

The driver will prompt for missed firmware blobs for a given platform.

[Where problems could occur]

New device to be supported for Jammy oem-6.0. May cause system stability
issues or power consumption performance.

[Other Info]

This device is supported since v5.19, so only Jammy (for oem-6.0) and Kinetic
are nominated for fix.
