intel_th: Add Memory Storage Unit driver
Memory Storage Unit (MSU) is a trace output device that collects trace data to system memory. It consists of 2 independent Memory Storage Controllers (MSCs). This driver provides userspace interfaces to configure in-memory tracing parameters, such as contiguous (high-order allocation) buffer or multiblock (scatter list) buffer mode, wrapping (data overwrite) and number and sizes of windows in multiblock mode. Userspace can read the buffers via mmap()ing or read()ing of the corresponding device node.
