The SPI master is connected to an Intel SPI Slave to Avalon Bridge inside an Intel MAX10 BMC Chip.

This driver supports SPI operations using FIFO mode of transfer. DMA is not supported, and we just use IRQ mode for operation completion notification. Only ACPI firmware is supported.

The SPI hardware in these SoCs is specifically intended for connecting NOR bootflash chips, and only used for that in dozens of examined devices. However boiled down to basics, it's really just a half-duplex SPI controller. The hardware appears to have a vestigial second chip-select control, but it hasn't been seen in the wild and is thus not supported.

Given that the only machine that is supported has only 4 MiB of RAM its use is also quite limited. Back then it served as the platform to develop ARMv7-M support in Linux which was quite fun and still is a blissful memory. Still given that the code serves no purpose and this probably won't change anytime soon, remove all platform support. I'm unsure what to do with the device tree bindings. Should we delete them, too?
