Multi-Lane SPI Support

For detailed information about Teensy 4.x LPSPI dual/quad-mode support:

• Platform Documentation: src/platforms/arm/teensy/teensy4_common/README.md - Complete LPSPI feature overview
• Implementation Guide: LP_SPI.md - Technical details for quad-mode pin configuration

Notes

• Very high CPU frequency; DWT-based timing and interrupt thresholds are critical for stability.
• OctoWS2811 and SmartMatrix can offload large parallel outputs; ensure pin mappings and DMA settings match board wiring.
