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.
