This checks if the DMA controller supports or not
the memory-to-memory transfers. For DMA Version1,
in the stm32f2xx, stm32f4xx, stm32f7xx series,
only DMA instance 2 is able to transfer mem-to-mem.
For other series, with DMA Version2, there is no such a limitation.

dts pinctrl definitions were pushed in tree without the code
available to deal with it. They have been kept waiting for the
code, but this is taking much more time than initially thought.
So in current zephyr tree, for all STM32 boards, we have pinmux.c
file which is used to configure pins and these files that are
basically no-op. This situation is creating a lot of confusion
especially to new comers, and create useless maintenance effort.
Remove these files for now.
When zephyr will ready to use them, this commit could be reverted.

There is no APB2 bus on stm32f0 series.
What could be found as APB2 in CMSIS files is actually
second group of APB (A.K.A APB1_2).
Fix nodes that are using this wrong reference accorss the series.

Update the ADC bindings to include #io-channel-cells and update the
related dts files to set #io-channel-cells.

The true mmio-sram nodes should not have had a 'device_type' property.
Remove it from the cases that we clearly know are SRAM.

All series of stm32 have at least one ADC instance and this commit adds
one ADC node to the root dts file of each soc, and also adds fixing up
mappings to them.

Add #pwm-cells to the STM32 PWM binding and dts files. This is to
support have a pwms clients work properly.

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 F0 dtsi files into their own dir.
