4f2c51e00d 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.

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.
