This provides an alternative esp32-specific SPI driver with ops that can be swapped in place of the gpio bitbang one. The pinmux info and lws gpio driver and other data in the spi bitbang struct are used as-is by the DMA one. New ops are provided which are able to allocate and free DMA-able memory so the device drivers can prepare directly usable buffers. Bounce through to DMA-able buffers is also transparently supported.
