Select the clock source dynamically on SoftDevice initialisation



Instead of relying on build macros to know which oscillator we're

supposedly using, check the value of LFCLKSRC register. This way, we can

trust mbed's init code to fallback on the internal clock if the user

specified a wrong target.

This change, along with the mbed patch that selects clock source

dynamically, will allow lots of application to still run and provide

FOTA, when the wrong Nordic platform is specified.
