70d200a03c rust: Resurrect interrupt test for second core 
It was disabled at some point because something in riscv-rt changed
and it no longer worked. Restore the testing in a more robust way.

68ddf3b1bc rust: Add function that directly hashes 32-bit units 
This is almost two times as fast, apparently, however it requires
the input to be aligned to 32 bit and be a multiple of 32 bits.
This should be special-cased.

fbe528d8b6 rust: Add assertion that input length is at least 0 for AES 
It doesn't look like the AES engine can handle 0-sized input. This makes
sense, in a way, as it is an edge case and in most cases a no-op. Only
in GCM mode, where there one might want to compute a tag over a 0-byte
input, would this come up.

7cc906d349 rust: Don't require resetting AES engine before every use 
When using the AES engine in GCM mode, the hardware *requires*
verifying a tag even if we don't care about the result. Otherwise it
will hang in unfinished state, and needs a reset every time.

By going through these motions (like the SDK does) this costly reset can
be avoided.

f1680533e4 k210-shared: Rewrite compute_params to use fixed-point 
This code is adapted from a patch I wrote for U-Boot "clk: Add K210 pll
support" Forty-Bot/u-boot@7d95737a93.
Significant reference was made to the datasheet for the PLL, which may be
found by searching for "tcitsmcn40ggpmplla1". For testing, I use a "brute
force" version of the algorithm which is significantly simpler code-wise.

ab95e18ba8 linux: Handle "SEND FAIL" response

we need to handle this, otherwise we'll never consider the send finished.

c261d4dcc7 linux: Simplify esptun by getting rid of some helper functions

integrate them.

7cbb10693e linux: Set timeout argument on poll() properly 
`0` for the timeout means *return immediately* instead of
*wait forever*. This is absolutely unnecessary, so change
the argument to `-1` which does mean *wait until something happens*.

aab7c0a84b linux: Solve an issue with incomplete packets 
esp_read_responses was throwing away the buffer contents between
invocations, which is not a good idea if there might be a (partial)
async notification such a a received packet in there.
