Benjamin Cabé cc4a985316 soc: rp2350: Add initial support for the Raspberry Pi RP2350 
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.
