 * @brief
 *   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 only if changing the core clock
 *frequency through the EFR 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.
