When RCC[TZEN] is enabled secure world needs to save the secure and non-secure clock configuration settings and restore them when resuming. Function stm32mp1_clk_mpu_suspend()/stm32mp1_clk_mpu_resume() are made local and renamed clk_mpu_suspend()/clk_mpu_resume(). The overall clock configuration is saved with stm32mp1_clock_suspend() and restored with stm32mp1_clock_resume().
