It includes the definition for the DMA peripheral of this type,
present on stm32U5 devices.
A particular DMA_STM32U5 config is selected for that purpose.
The driver is derived from the existing dma_stm32.c
The GPDMA is counting channels (0-15) ; stream offset is 0.

According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes
in this patch:
sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig*

This is the dma V2bis which is particular DMA V2 instance for
stm32F1 and STM32L1 soc series. This DMA does not use the dma slot
Otherwise it is similar to version V2.

Update the existing driver to support STM32G0 series.
It enables the DMA_STM32_SHARED_IRQS flag for g0 series, such that
all interrupts are handled in a shared isr to avoid irq conflicts.
The shared isr is extended to be able to handle irqs from more than one
dma instance.
Furthermore the config_irq function of instance 1, which connects to the
irqs, was reworked to avoid irq conflicts when 2 dma instances on
stm32f0, or stm32g0 are enabled:
While dma1 has one exclusive irq for channel 1, and one irq for dma1
channels 2 and 3, all other channels share the same irq.
Therefore it is currently not possible to enable dma2 without enabling
dma1 at the same time, without getting an build errror due to an irq
conflict.

Add the missing parts for adding support
to stm32h7 dma driver.
The fix is to make dmamux driver work with
dma v1 driver.

In order to simplify the handling of DMA_STM32_V1/V2 and DMAMUX_STM32
symbols, set them directly based on related compatible status.

The dmamux requires HEAP size definition, so that k_malloc
is valid. The HEAP size config is defined in the common for
any stm32 soc instead of specific to dma Kconfig

The general DMA driver doesn't use kmalloc anymore so it doesn't
need a memory pool. The DMAMUX_SMT32 driver still uses kmalloc,
so move the HEAP_MEM_POOL_SIZE config under DMAMUX_STM32.

- Remove the need for kmalloc
- On hardware that supports it use 1 IRQ handler per stream to
determine the stream ID, so the ISR does not have to loop
over all ID's to see which one is active. On hardware (like
STM32L0 and STM32F0) where up to 7 streams share 3 IRQ's use
the loop to check which stream is active.

This patch prepares the dma and introduces the dmamux on soc series
which supports this feature for memory/periph transfers.

when DMA IP is enabled on stm32 series,
the heap size must be configured to large value
because of dma channels configuration.

This commit adds driver support for DMA on f0/f1/f2/f3/f4/l0/l4
series stm32.
Notice due to some bugs, this is currently not working with f7.
There are two kinds of IP blocks are used across these stm32, one is the
one that has been used on F2/F4/F7 series, and the other one is the one
that has been used on F0/F1/F3/L0/L4 series.
Memory to memory transfer is only supported on the second DMA on
F2/F4 with 'st,mem2mem' to be declared in dts.
This driver depends on k_malloc to allocate memory for stream instances,
so CONFIG_HEAP_MEM_POOL_SIZE must be big enough to hold them.
Common parts of the driver are in dma_stm32.c and SoC related parts are
implemented in dma_stm32_v*.c.
This driver has been tested on multiple nucleo boards, including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/L073RZ/L476RG with the
loop_transfer and chan_blen_transfer test cases.
