circuitpython/ports/stm32/mpconfigport.h
Jim Mussared 902bb4ceae stm32: Extract port-specific Nimble implementation. 
On other ports (e.g. ESP32) they provide a complete Nimble implementation
(i.e. we don't need to use the code in extmod/nimble). This change
extracts out the bits that we don't need to use in other ports:
 - malloc/free/realloc for Nimble memory.
 - pendsv poll handler
 - depowering the cywbt

Also cleans up the root pointer management.
