Don't acquire the spi bus in the display driver
...
Interrupt-based transactions don't need it, and it causes issues.

Use only one buffer for lvgl's display driver
...
We weren't actually making use of the double buffering, and it's a pain

Use interrupt-based spi for the display
...
This solves our "audio stutters while scrolling" problem better! Turns
out the real root cause was the polling SPI driver blocking a whole CPU
during playback.
