8e22d57447 rp/pio: add hd44780 example
add an hd44780 example for pio. hd44780 with busy polling is a pretty
complicated protocol if the busy polling is to be done by the
peripheral, and this example exercises many pio features that we don't
have good examples for yet.

1414: rp: report errors from buffered and dma uart receives r=Dirbaio a=pennae

neither of these reported errors so far, which is not ideal. add error reporting to both of them that matches the blocking error reporting as closely as is feasible, even allowing partial receives from buffered uarts before errors are reported where they would have been by the blocking code. dma transfers don't do this, if an errors applies to any byte in a transfer the entire transfer is nuked (though we probably could report how many bytes have been transferred).

f4ade6af8b rp/pio: write instr memory only from common
instruction memory is a shared resource. writing it only from PioCommon
clarifies this, and perhaps makes it more obvious that multiple state
machines can share the same instructions.

this also allows *freeing* of instruction memory to reprogram the
system, although this interface is not entirely safe yet. it's safe in
the sense rusts understands things, but state machines may misbehave if
their instruction memory is freed and rewritten while they are running.
fixing this is out of scope for now since it requires some larger
changes to how state machines are handled. the interface provided
currently is already unsafe in that it lets people execute instruction
memory that has never been written, so this isn't much of a drawback for now.

58e727d3b9 rp/pio: move non-sm-specific methods to PioCommon
pin and irq operations affect the entire pio block. with pins this is
not very problematic since pins themselves are resources, but irqs are
not treated like that and can thus interfere across state machines. the
ability to wait for an irq on a state machine is kept to make
synchronization with user code easier, and since we can't inspect loaded
programs at build time we wouldn't gain much from disallowing waits from
state machines anyway.

12d6e37b3f Example using the PIO to drive WS2812 aka Neopixel RGB leds
This example also uses a pio program compiled at runtime, rather than one built at compile time. There's no reason to do that, but it's probably useful to have an example that does this as well.

3af991ab63 usb: unify ControlHandler+DeviceStateHandler, route all control requests to all handlers.
- Allows classes to handle vendor requests.
- Allows classes to use a single handler for multiple interfaces.
- Allows classes to access the other events (previously only `reset` was available).

984: rp pico async i2c implementation r=Dirbaio a=jsgf

This implements an interrupt-driven async i2c master. It is based on https://github.com/embassy-rs/embassy/pull/914, a bit of https://github.com/embassy-rs/embassy/pull/978 and `@ithinuel's` https://github.com/ithinuel/rp2040-async-i2c.git

This is still work-in-progress, and is currently untested.

1006: Removes some of the code duplication for UarteWithIdle r=Dirbaio a=huntc

This PR removes some of the code duplications for `UarteWithIdle` at the slight expense of requiring a split when using idle processing. As the nRF example illustrates though given the LoC removed, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this PR was actually due to the `event_endtx` method not having been copied across to the idle-related code.

Tested the uart_idle example on my nRF52840-dk, and from within my app. Both appear to work fine.
