disable onewireio on seeduino xiao (samd21) 
I don't understand how this stopped fitting, as none of the added code
is used in this build.

rp2pio: Add pull up/down support for the "jmp pin" 
This is needed so that the floppy flux reader can enable the pull up
on the index pin while using it as a pio jmp pin.

Also fixes a doc bug where the `jmp_pin` was omitted in one spot in the docs.

Add floppyio for rp2040 
Tested on RP2040 Feather with a 3.5" Prodigy diskette, the whole
surface reads 100% across 3+ trials.

Add floppyio 
Initially enabled for samd51, this enables reading raw flux data as well
as DOS/MFM formatted media.

This is only the low-level code for reading & decoding flux pulses from a floppy drive.
high level details will live in a Python library.

adafruit-circuitpython-floppy will take care of details like stepping
from track to track, etc.

Add a function to get low level register access 
The port is free to return NULL for any/all of these, and the caller has
to check.

This will be used in the floppy code, because aside from getting the
registers, it looks like all is independent of MCU.

8226fb8e0b Bring pins in line with board documentation. 
This brings the pins in line with the documented [pinouts]. The only
"special" pins:

 - GP0, GP1 are mentioned as the default UART, so we init them as
   such and give them the TX and RX alternative names.
 - GP16 is connected to the onboard neopixel DIN line and we assign it
   the NEOPIXEL name. (Power of the neopixel is connected to the 3.3V
   rail, not a pin. See [schematic].)
 - GP26, GP27, GP28, GP29 have unambiguous ADC designations in the
   [pinouts], so we assign the `A` analogue names as the Pico board
   definition does.

  [pinouts]: https://www.waveshare.com/wiki/RP2040-Zero#Pinouts

raspberrypi : Check UART before claiming pins, claim it after

raspberrypi: Claim UART after checking pins 
If, for some reason, you mix up TX and RX when calling `busio.UART` (who would do that ;) ), you get `Invalid pins`. When you go to try again, you'll get `All UART peripherals are in use` because the interface was claimed as busy before pins are verified. This should fix that issue.

done. :-)
