Kan Liang a50d03e3b8 perf sort: Add sort option for data page size 
Add a new sort option "data_page_size" for --mem-mode sort.  With this
option applied, perf can sort and report by sample's data page size.

Here is an example:

perf report --stdio --mem-mode
--sort=comm,symbol,phys_daddr,data_page_size

 # To display the perf.data header info, please use
 # --header/--header-only options.
 #
 #
 # Total Lost Samples: 0
 #
 # Samples: 9K of event 'mem-loads:uP'
 # Total weight : 9028
 # Sort order   : comm,symbol,phys_daddr,data_page_size
 #
 # Overhead  Command  Symbol                        Data Physical
 # Address
 # Data Page Size
