[STM32] remove superfluous calls to SystemCoreClockUpdate 

Supported toolchains initialization steps have been modified to make sure
that mbed_sdk_initi is called _after_ RAM initialization and _before_ C++
objects creation.

since this was done, there is no need to redundant SystemCoreClockUpdates
in the drivers
