Add initial support for the RP2350's DMA peripheral, allow tests
under drivers/dma/loop_transfer to run on on the Raspberry Pi Pico 2,
and update the board's documentation.

Add initial support for the RP2350's PIO peripherals, extend the
existing example under samples/boards/raspberrypi/rpi_pico/uart_pio to
demonstrate this on the Raspberry Pi Pico 2, and update the board's
documentation.

RP2350 is Raspberry Pi's newest SoC. From the datasheet:
"RP2350 is a new family of microcontrollers from Raspberry Pi that
offers significant enhancements over RP2040. Key features include:
• Dual Cortex-M33 or Hazard3 processors at 150 MHz
• 520 kB on-chip SRAM, in 10 independent banks
• 8 kB of one-time-programmable storage (OTP)
• Up to 16 MB of external QSPI flash/PSRAM via dedicated QSPI bus
...
"
This commit introduces some changes to support the existing RP2040 and
what is describe by Raspberry Pi as the "RP2350 family". Currently there
are 4 published products in the family: RP2350A, RP2350B, RP2354A, and
RP2354A. Within Zephyr's taxonomy, split the configuration as follows:
Family: Raspberry Pi Pico. This contains all RP2XXX SoCs,
SoC Series: RP2040 and RP2350.
SoC: RP2040 and, for now, just the RP2350A, which is present on the Pico
2, where the A suffix indicates QFN-60 package type. This structure is
reflected in `soc/raspberrypi/soc.yml`, and somewhat assumes that there
won't be a RP2050, for example, as a RP2040 with more RAM.
This is foundation work ahead of introducing support for Raspberry Pi's
Pico 2 board, which is fitted with a RP2350A and 4MB of flash.

Add support for SoC-specific clock ids and update the initialization
function to support the existing RP2040 and add support for the RP2350.
clock_control_rpi_pico.c uses numerical values for clock ids taken from
rpi_pico_clock.h which are the "clock generator". For the RP2350 these
values are different for some of the same logical clock sources, as well
as the RP2040 and RP2350 having different clock sources available.

Rename rpi_pico_common.dtsi to rp2040_reset.h . This is more consistent
with the wider Zephyr source tree, and is foundation work ahead of
introducing the RP2350 SoC.
Add missing include guard. This shouldn't be required, but it is
consistent with other header files in the same directory.

Follow the wider directory convention of dts/<arch>/<vendor>/<family>.
This is foundation work ahead of introducing support for the RP2350.
