aspeed: Add Supermicro X11 SPI machine type
supermicrox11-bmc is configured with ast2400-a1 SoC. This does not match the Supermicro documentation for X11 BMCs, and it does not match the devicetree file in the Linux kernel. As it turns out, some Supermicro X11 motherboards use AST2400 SoCs, while others use AST2500. Introduce new machine type supermicrox11-spi-bmc with AST2500 SoC to match the devicetree description in the Linux kernel. Hardware configuration details for this machine type are guesswork and taken from defaults as well as from the Linux kernel devicetree file. The new machine type was tested with aspeed-bmc-supermicro-x11spi.dts from the Linux kernel and with Linux versions 6.0.3 and 6.1-rc2. Linux booted successfully from initrd and from both SPI interfaces. Ethernet interfaces were confirmed to be operational.
