hw/arm/aspeed: add anacapa-bmc machine
Add the Facebook Anacapa BMC machine. The I2C topology is based on the Linux kernel device tree [1]. Hardware strap register values are taken from real hardware. A functional test is included using the OpenBMC image built from [2], similar to the tests for bletchley-bmc and catalina-bmc.
