perf/x86/intel: Support PERF_SAMPLE_DATA_PAGE_SIZE
The new sample type, PERF_SAMPLE_DATA_PAGE_SIZE, requires the virtual
address. Update the data->addr if the sample type is set.
The large PEBS is disabled with the sample type, because perf doesn't
support munmap tracking yet. The PEBS buffer for large PEBS cannot be
flushed for each munmap. Wrong page size may be calculated. The large
PEBS can be enabled later separately when munmap tracking is supported.
