The Primary-to-Sideband bus (P2SB) is used to access various peripherals through memory-mapped I/O in a large chunk of PCI space. The space is segmented into different channels and peripherals are accessed by device-specific means within those channels. Devices should be added in the device tree as subnodes of the p2sb.
This adds a uclass and enables it for sandbox.
