Radxa Zero 3: Fix 3W's Bluetooth Support

Browse Source 
Bluetooth on the 3W was non-functional. Required functions are copied
from radxa-cubie-a5e.csc (also used in kickpik2b.csc). These should
ideally be extracted into a shared location.

The antenna switch (internal vs external) is still missing. Radxa
implements this via DT overlays and their rsetup tool:
  https://docs.radxa.com/en/zero/zero3/os-config/rsetup\#overlays
  https://github.com/radxa-pkg/radxa-overlays/blob/main/arch/arm64/boot/dts/rockchip/overlays/radxa-zero3-external-antenna.dts

Only tested on 3W; impact on 3E is unknown. The functions and packages
should ideally be limited to 3W builds, but this seems impossible
without splitting the CSC file.
