RP2350 pioasm .fifo putget configuration description

In the _pioasm_ documentation of the _pico-series C/C++ SDK_, and of the _RP2350 datasheet_ as well, it looks like the entry `putget` for directive `.fifo ` should be something like...

It would be nice to have a few more diagrams of the interpolator configurations with some more details, like in the examples given below (no guarantee of correctness, though): 

Some PIO examples are not working on RP2350/Pico 2

`MicroPython v1.25.0-preview.187.g1b4c969ce on 2025-01-14; Raspberry Pi Pico2 with RP2350` [`pio_1hz.py`](https://github.com/raspberrypi/pico-micropython-examples/blob/master/pio/pio_1hz.py) prints: `ValueError: freq out of range` A quick fix would probably be `machine.freq(125_000_000)` but the LED only switches on and...

Diff suggested in #2312.

Diff suggested in #2163. Requires rebuild of flex/bison targets (and pioasm docs updates).

OK, there seems to be still some inconsistency. If ``` .program test .side_set 0 opt jmp 0 side 0 ``` is allowed (I'm assuming `side 0` with `.side_set 0 opt`...

enum gpio_override missing in SDK documentation

Was mentioned in https://github.com/raspberrypi/pico-sdk/issues/265#issuecomment-801522889 but [still](https://forums.raspberrypi.com/viewtopic.php?p=2304973#p2304973) (or again) an issue.

Some entries for macros missing in generated docs

It looks like some macro entries like for `__not_in_flash(group)` or `__not_in_flash_func(func_name)` are missing in the online and PDF docs. Actually, their _example_ entries are there but under `__scratch_x(group)` and `__no_inline_not_in_flash_func(func_name)`...
