rockchip-vendor: CONFIG_BT_HCIBTUSB=m

[vidplace7]

Description

Enable CONFIG_BT_HCIBTUSB=m generic USB Bluetooth support for rockchip-vendor kernel.

How Has This Been Tested?

• Compiled for BOARD=luckfox-lyra-zero-w BRANCH=vendor RELEASE=trixie BUILD_MINIMAL=yes INSTALL_HEADERS=yes INSTALL_ARMBIAN_FIRMWARE=yes successfully
• Ensured no bluetooth regressions with AIC8800 (builtin on many rockchip boards).
  radxa-aic8800 uses a different module and they don't appear to conflict.

rfkill unblock all
systemctl restart bluetooth.service
bluetoothctl
# inside bluetoothctl

• Confirmed btusb loads properly (usb bluetooth dongle + modprobe)
