rust: Unswizzle framebuffer for ST7789V display
...
By swapping the endian in RAMCTRL as well as in the SPI driver,
the frame format can be coerced into the "normal" order of pixels in
little endian, `0xBBBBAAAA` instead of `0xAAAABBBB`. This allows
seamless casting from an array of `u16`.
Accessing as 32-bit units might still be desirable for performance, but
it is a lesser worry now.
Note that a 32-bit alignment constraint still does hold for DMA.

This is almost two times as fast, apparently, however it requires

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.

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.

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.

This mimics the way the Kendryte SDK does things—it is better because
the MMIO based SPI tends to sometimes lose synchonization when the CPU
doesn't keep up providing data fast enough.

Add basic DMAC support (SPI/LCD first).
The current implementation (adding _dma to LCD traits) is really, really
awkward and just for testing. Probably it would be better for the LCD to
own its own dedicated DMA channel to avoid having to pass them in
for every… single… thing…
