microbit: Added read capability to MicroBitDFUService::ControlPoint characteristic

Browse source 
Whilst Android devices permit explicit initiation of the BLE pairing process,
IOS based devices are only  capable of implicit initiation of pairing based
on accessing a protected characteristic. Adding read capability to the
ControlPoint characteristic provides a safe and convenient way for IOS devices
to initiate pairing.
