Subject: Fix Skylake PEBS data source for perf v5

Fix data source reporting for Skylake and Skylake Server.
The encodings have changed to express support for L4 and persistent
memory. 

The first patch is a (independent) cleanup.

The second is for the kernel and the third/fourth for perf/tools.
The kernel part and perf tools will compile independently.

git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc.git perf/skx-data-src-7
