soc/intel/common: Add Intel Trace Hub driver
From Meteor Lake onwards Intel FSP will generate the Trace Hub related
HOB if the Trace Hub is configured to save data in DRAM. This memory
region is used by Trace Hub to store the traces for debugging purpose.
This driver locates the HOB and marks the memory region reserved so
that OS does not use it.
Intel Trace Hub developer manual can be found via document #671536 on
Intel's website.
