[PATCH] clk: stm32: add configuration flags for each of the stm32 drivers

From: Benjamin Gaignard
Date: Mon Jan 15 2018 - 09:22:13 EST


Add two configuration flags to be able to not compile all the time
stm32f and stm32h7 drivers when ARCH_STM32 is set.
That help to save some space on those small platforms.
