Bug description:
[SRU Justification]
[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.

[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.
