On various stm32 soc packages CCM is available and SRAM size
mentionned in datasheet include CCM.
Though, actual SRAM size defined in dtsi files should not
include CCM sizes.
Fix this on impacted dtsi files.

To move forward and remove use of Kconfig in dts files lets just create
SoC specific dtsi files that the boards can include. We also seperate
out the F4 dtsi files into their own dir.
