* Update CMSIS SystemCoreClock variable.
*
* @details
* CMSIS defines a global variable SystemCoreClock that shall hold the
* core frequency in Hz. If the core frequency is dynamically changed, the
* variable must be kept updated in order to be CMSIS compliant.
*
* Notice that if only changing core clock frequency through the EFM32 CMU
* API, this variable will be kept updated. This function is only provided
* for CMSIS compliance and if a user modifies the the core clock outside
* the CMU API.
