* Fix Async UART
The uart handler was `writing` to the enable register instead of
`modify`, which meant any wake would see the cleared enabled bit and
think the event had occurred. This wasn't seen before the split of uart
because it was only possible to listen to one thing at a time.
This PR also removes the ReadBufferFull error in favour of returning the
max bytes in the buffer.
The serial examples has been updated to actually have some cross task
communication.

* Duplicate spi to spi_slave
* Restore spi
* Add barebones SPI slave mode, DMA only.
This setup allows registering buffers for future transactions the master
does (lowering cs, toggling sclk, and raising cs again). The transfer
struct returned from the registration API will complete its wait() or
return true from is_done() after cs has been raised.
Copied from spi.rs, so most of the changes are deleting code that
handles e.g. segmented transfers or synchronous operations.
Fix non-c3 devices' builds
* Limit spi_slave to non-pdma devices
* SPI slave DMA example
Ensure the API "feels" right.
Since there's no way to route GPIOs to other peripherals, we choose four
other wires and bit-bang SPI for the master side, relying on the person
running the example to connect the bus. This way we ensure the slave
code works, since we created the master ourselves.
Also, it's not really possible to use a second ESP device as the master
anyway: all the digital lines have glitches on startup, and those
glitches cause the slave's DMA engine to skip descriptors (it thinks
they're intended CS indicators); this causes it to lose data.
Then, fix the bitbang master (recording the progression here)
- When bitbanging, iterate the bits by "for _ in 0..8", instead of the
broken "for _ in [0..8]". The latter only runs the iteration once,
since there's only one list given ... and because the code uses _
instead of a real loop variable, type checking didn't save us.
- When bitbanging, send the bits out (and read them in) MSB first, since
that's actually how we have the slave configured.
* Add changelog entry
* Split DMA prepare_transfer into two fns.
The first does everything but write to the start bit and check for an
error. The second does those. We need 2 fns because the SPI slave needs
to start the transfer only after resetting the various afifo hardware
components (if it starts the transfer before, the first 8 bytes will be
lost when that reset happens).
Use the split fns everywhere.
Also split flush(). It needs to be pollable, so split it into one fn that
polls and one that waits until the poll returns clear. Also call the poll
fn from the is_done() fn, so we don't trample in-progress transfers.
* Make example code fill rx buffer before transfer
This way we can tell if it's ever touching certain bytes - 0xff is never
added to the master transmit buffer.
While I'm changing this, make the slave tx buffer never contain 0xff
either (go from 254 to 0).
