Wladimir J. van der Laan 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.
