Remove address-of operator ('&') when assigning `dma_xxx_init`
function pointer in `DEVICE_DT_INST_DEFINE` macro.
This change aims to maintain consistency among the drivers in
`drivers/dma`, ensuring that all function pointer assignments
follow the same pattern.

Some instances of DMA (dma0) can use the normal sram to store their
descriptors. In this case, it makes sense to allow the linker to
allocate the memory rather than tweaking the memory layout.
So, if the attribute silabs,sram-region is not defined, use a statically
allocated buffer.

Silabs siwx91x hardware use specific memory areas to store descriptors
for DMA requests. These areas are tightly coupled between the CPU and
the hardware. This helps in reducing the wait cycles.
Until now these addresses was also hard coded in the DT and in the
linker script. This patch leverage the zephyr,memory-region driver to
centralize the information in the DT.
Then, with this new implementation, the memory mapping is easier to
understand for the reader.

DMA channel capacity wasn't properly initialized and the computation
relies on it being zeroed.
This only works fine only when requesting channel the first time
causing problems when we have multiple cycles of channel
request/release.
Fix this by properly initializing the capacity when requesting the
channel.

#84065 replaced diagnostic pragmas with TOOLCHAIN_* macros, but we don't

Add support for 8-channel configurable DMA controller. The driver
supports the following features:
- memory to peripheral (ch0 to ch5)
- peripheral to memory (ch0 to ch5)
- memory to memory (ch6 and ch7)
Each DMA channel is multiplexed between two or more trigger sources:
- ch0 -> SPI0_TX or UART0_RX
- ch1 -> SPI0_RX or UART0_TX
- ch2 -> LRFD or UART0_TX
- ch3 -> ADC0 or UART0_RX
- ch4 -> AES_A or LRFD
- ch5 -> AES_B or ADC0
- ch6 -> Software Event Channel 0
- ch7 -> Software Event Channel 1
