This commit continues simplifying the generation of
isActiveFlag/clearFlag funtion pointer array for the request generators
and does the same for the table_ll_channel.
Additionally move struct dmamux_stm32_channel to c file.

This commit uses dt property dma-channels instead of ll defines to
make sure every soc has correct number of function pointers defined.
While commit 5f6218a tried to fix this for g0 series, this caused
regression for other series(e.g. stm32g431). Using UTIL_LISTIFY and
dt properties this should finally be fixed and reduce boilerplate code.

1. Update the SDK API's called in the configure implementation.
The DMA_PrepareTransfer and DMA_SubmitTransfer SDK functions
are not recommneded for use. Replaced the call to these SDK
functions with other SDK API's.
2. Fix the implementation the configure function when multiple
blocks are used.
3. Update the dma_reload implementation. The old reload function
would simply abort the transfer. The new implementation reloads
the DMA buffers for transfer.

Fix stm32_dma_is_irq_active not checking the IRQ status(IsEnabled) for
active interrupts.
While the transfer-complete, half-transfer comp. and transfer-error
is_XX_irq_active() functions check for IRQ status (IsEnabled),
ORing the result with dma_stm32_is_gi_active() overrides the
status check as gi is always 1 in case any of these flags is active.

Use LL_DMAMUX_CHANNEL_x defines instead of DMAMUX_CSR_SOF7x to check
if corresponding LL_DMAMUX_IsActiveFlag_SOx and LL_DMAMUX_ClearFlag_SOx
inline functions exist and should be added to func_ll_is_active_so[]
and func_ll_clear_so[].
The HAL of some socs uses the same flag to decide which registers exist
on a specific soc. And the same defines are used for table_ll_channel[]
initializations.
This is necessary because DMAMUX_CSR_SOF5 and DMAMUX_CSR_SOF6 were
wrongly added in the HALs soc header file for some stm32g0 socs,
therefore without this change some stm32g0 socs couldn't compile.

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.

Not all STM32 Series can enable a dedicated clock for dmamux.
In stm32g0 series for example the clock is enabled automatically
as long as either DMA1 or DMA2 is enabled.
This commit changes dmamux driver to cope with socs that don't have
defined a clocks property. Therefore it moves the config(and data)
struct into the c file to be able to use DT_INST_NODE_HAS_PROP macro.

When running the tests of the async api of uart
on nucleo-l4r5zi we get MPU fault.
The reason is ordering initialization. The uart and dma
drivers are initialized PRE_KERNEL_1 while dmamux is
initialized POST_KERNEL.
Thus, the function device_get_binding fails since the
dmamux device is not ready to be used.
Fixes: #32715.

Move dmamux_stm32_channels struct from device data to device
configuration and initialize the dmamux channel - dma channel
assignment during build time,
as this association is hardwired in all known series.
The information is taken from dma_offset and dma_requests device tree
properties. The current implementation is valid for series with either
a single or two dma peripherals and a single dmamux peripheral.
Both dmas can independently enabled.
As the driver uses multi-instance DT_INST_DEFINE, also macros for a
second dmamux are are added that should allow easier extension to a
second dmamux instance.

The stm32_dma_disable_stream first checked if the stream was
disabled and if so returned OK. If it wasn't disabled it
tried to disable it and returned -EAGAIN.
The function is used in loops that try to disable the stream
by calling this function and if it fails wait for 1ms and
retry.
Becuase this function the first time (if the stream wasn't
disabled already) fails there is always a 1 ms delay. For
the SPI driver, that has a RX and TX stream, this means
a 2ms delay between the last data and CS going high.
By first trying to disable the stream and than checking
if it succeded most of the time the first call disables
the stream and the 1ms delay isn't needed.
