powerpc/pseries/htmdump: Add htm flags support to htmdump module
Under debugfs folder, "/sys/kernel/debug/powerpc/htmdump", add file
"htmflags". Currently supported flag value is to enable/disable
HTM buffer wrap. wrap is used along with "configure" to prevent
HTM buffer from wrapping. Writing 1 will set noWrap while
configuring HTM
