a10850a6da rp/pio: handle all pio irqs in one handler
dma does this too, also with 12 bits to check. this decreases code size
significantly (increasing speed when the cache is cold), frees up an
interrupt handler, and avoids read-modify-write cycles (which makes each
processed flag cheaper). due to more iterations per handler invocation
the actual runtime of the handler body remains roughly the
same (slightly faster at O2, slightly slower at Oz).

notably wakers are now kept in one large array indexed by the irq
register bit number instead of three different arrays, this allows for
machine code-level optimizations of waker lookups.

1406: rp: DMA behaviour during flash operations r=Dirbaio a=kalkyl

This PR changes the old behaviour during flash operations where all DMA transfers were paused during the flash operation.
The new approach is to wait for any DMA operating in flash region to finish and let RAM transfers continue.

We shouldn't have Cargo features if their only purpose is reduce cold build time a bit.

fdd6e08ed6 rp: hook up softfloat rom intrinsics
rp-hal has done this very well already, so we'll just copy their entire
impl again. only div.rs needed some massaging because our sio access
works a little differently, everything else worked as is.

1378: Add ability to invert UART pins, take 2 r=Dirbaio a=jakewins

Same PR as before, except this now works :) 

There was a minor hiccup in the UartRx code where the rx pin got passed as the tx argument, so the invert settings didn't get applied. With this fix, my local setup at least is happily reading inverted uart data.

1372: rp: add division intrinsics r=Dirbaio a=pennae

rp2040-hal adds division intrinsics using the hardware divider unit in the SIO, as does the pico-sdk itself. using the hardware is faster than the compiler_rt implementations, and more compact too.

since embassy does not expose the hardware divider in any way (yet?) we could go even further an remove the state-saving code rp2040-hal needs, but that doesn't seem to be worth it.

This is useful in some cases where the surrounding circuit
for some reason inverts the UART signal, for instance if you're talking
to a device via an optocoupler.

1fbb8f0b32 feat(rp): add Wait impl to OutputOpenDrain
A while ago `OutputOpenDrain` was made to implement `InputPin`,
something that allowed drivers for various one-wire protocols to be
written, but it's been lacking a `Wait` implementation — something
that's needed to write async versions of these drivers.

This commit also adds `get_level()` to `OutputOpenDrain`, since
`is_high()` and `is_low()` were already implemented, but `get_level()`
itself was missing.
