spi: speed up bit banging and special case everything

This patch significantly improves SPI throughput by avoiding
many duplicated writes. For example, we now only adjust the MISO
direction once during every byte rather than for every bit.
This improves the time it takes to upload a 128 kilobyte file from 29
seconds to 6 seconds.
