Include all RCC, clocks and reset headers from stm32mp1_def.h which if exported to the firmware through platform_def.h. The same dependency removal is done in common code as well. Some useless includes are also removed in stm32_sdmmc2 driver. Change-Id: I731ea5775c3fdb7f7b0c388b93923ed5e84b8d3f Signed-off-by: Yann Gautier <yann.gautier@st.com>
