Feature: RP2350 A and B variant #2381

Discussed in https://github.com/earlephilhower/arduino-pico/discussions/2371

Originally posted by **elral** August 26, 2024 The new RP2350 is available in variant `A` and `B`. The `A` variant has the same number of pins as the RP2040 where the `B` variant has 40 pins (and at least the analog pins on another pins). For now there is one generic variant for the RP2350. I am wondering if it would make sense to mark this variant as `A` and setup another one for variant `B`. Yesterday I moved our project from platformIO to the Arduino IDE to test it with the RP2350. For what I could test everything was working fine (except AnaologIn as I am using an PGA2350, but will test it with a Pico2 again). Really great job!! Thanks a lot for your effort!

A quick look through the SDK seems to indicate there is no actual SDK difference between the two. So, only one rp2350/libpico.a needed. Only real ugly bit will be the PIO GPIOBASE conversion which does GPIO shifting on a per-PIO (not SM or program) basis. Need to modify PIOProgram to be aware of the and manage it...
