RP2350 support

[leondisctech]

Hi @petewarden

I realize that the Pico 2 (and RP2350 chip) aren't widely available yet, so it may not be possible to answer this question yet, but I'll ask anyway:

Will pico-tflmicro will work out of the box with the RP2350 or if it will take some tweaking?

(I recall that getting two cores to work on the RP2040 required digging into the details of the RP2040's memory layout, so supporting the RP2350 may require something similar.)
