 * Name: stm32l5_flash_user_optbytes
 *
 * Description:
 *   Modify the contents of the user option bytes (USR OPT) on the flash.
 *   This does not set OBL_LAUNCH so new options take effect only after
 *   next power reset.
 *
 * Input Parameters:
 *   clrbits - Bits in the option bytes to be cleared
 *   setbits - Bits in the option bytes to be set
 *
 * Returned Value:
 *   Option bytes after operation is completed
