rp2/mpbthciport: Remove mp_bthci_uart from set of root pointers. 

This is a statically-allocated UART (see machine_uart.c), and doesn't
contain any heap pointers other than the ringbufs (which are already root
pointers), so no need to track it additionally.

Saves needing to add mpbthciport.c to the QSTR sources.
