Load the full hardware config up front rather than only the GPIO section,
so display settings can come from the same file. Adds a rotate parameter
that falls back to display.rotate in the config when not passed
explicitly, and logs the resolved value.
Also bumps the dreader-hal submodule to 64c9177 (use partial draw) and
adds a direct IT8951 example that bypasses the HAL, for isolating display
problems to the driver layer.
