We want to add additional sub-classes for TRC_PV tracepoints and to be able to only capture these new sub-classes. This cannot currently be done as the existing tracepoints all use a sub-class of 0xf. So, redefine the PV events to use a new sub-class. All the current tracepoints are tracing entry points to the hypervisor so the sub-class is named TRC_PV_ENTRY. This change does not affect xenalyze as that only looks at the main class and the event number and does not use the sub-class field.
