The DMA driver of stm32 used to use `stm32_dma_enable_fifo()`,
which is located in dma_stm32_v1.c to set DMDIS bit, enable
interrupt generation and set FIFO threshold. Now since FIFO
threshold is initialized with `stm32_dma_get_fifo_threshold()`
and interrupt generation is also configured in dma_stm32.c, this
function will only have one job, to configure FIFO mode.
We can add FIFO mode operation in dma_stm32.c directly and
remove it from dma_stm32_v1.c.

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.

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'
I tweaked Kconfiglib a bit to find most of the stuff.
Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.
Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.
[*] Enable foo ---
This is how it would be shown if there were children but they all
happened to be invisible as well.
With a regular 'config', it turns into
[*] Enable foo
Change all pointless 'menuconfig's to 'config's.
See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

These calls are not accessible in CI test, nor do they get built on
common platforms (in at least one case I found a typo which proved the
code was truly unused). These changes are blind, so live in a
separate commit. But the nature of the port is mechanical, all other
syscalls in the system work fine, and any errors should be easily
corrected.

Implement the get_status DMA API for the SAM0 DMA controller.
The busy field is set only when the selected channel is
actively transferring data (i.e. both enabled and selected by the
arbiter). The direction field is left unset, since that
information is not normally retained by the DMA controller.

Some applications using DMA, such as UART RX, could
need to complete the current DMA transaction earlier than
predefined, based on other termination conditions,
like UART's IDLE interrupts.
In that case, the client needs to know how many data are
still left in DMA transfer buffer so that it can figure
out how many data has been transfered. However, the current
DMA API doesn't provide any information for the client
to learn the transfer buffer information.
And some other information, like whether DMA transfer is busy
or not, transfer direction, etc, could interest a client.
So, added a dma API function to retrieve the current DMA
runtime status.
And implemented the API for STM32F4's DMA while keeping
others unimplemented.

The dma_reload() is useful when there's the need to immediately
and quickly restart the DMA for a new transfer when the current
one is completed. If the operation is not done quickly there
might be underrun or overrun errors and the data flow is broken.
The dma_reload() just does the minimum operations required, i.e.
programming the new src/dst addresses and transfer size.
