Bluetooth: btbcm: Add entry for BCM4335C0 UART bluetooth

This patch adds the device ID for the AMPAK AP6335 combo module used
in the 1st generation WeTek Hub Android/LibreELEC HTPC box. The WiFI
chip identifies itself as BCM4339, while Bluetooth identifies itself
as BCM4335 (rev C0):

```
[    4.864248] Bluetooth: hci0: BCM: chip id 86
[    4.866388] Bluetooth: hci0: BCM: features 0x2f
[    4.889317] Bluetooth: hci0: BCM4335C0
[    4.889332] Bluetooth: hci0: BCM4335C0 (003.001.009) build 0000
[    9.778383] Bluetooth: hci0: BCM4335C0 (003.001.009) build 0268
```
