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.

Additional missing-prototypes fixes 
I think this correctly enables missing-prototypes in atmel-samd
and raspberrypi ports.

Implement audiobusio and enhance PIO for it 
This adds I2SOut and PDMIn support via PIO.

StateMachines can now:
 * read and read while writing
 * transfer in 1, 2 or 4 byte increments
 * init pins based on expected defaults automatically
 * be stopped and restarted
 * rxfifo can be cleared and rxstalls detected (good for tracking when
   the reading code isn't keeping up)

Fixes #4162
