Ingo Molnar 1784f9144b drivers/misc/intel/pti: Rename the header file to free up the namespace
We'd like to use the 'PTI' acronym for 'Page Table Isolation' - free up the
namespace by renaming the <linux/pti.h> driver header to <linux/intel-pti.h>.

(Also standardize the header guard name while at it.)

* The PTI (Parallel Trace Interface) driver directs trace data routed from
* various parts in the system out through the Intel Penwell PTI port and
* out of the mobile device for analysis with a debugging tool
* (Lauterbach, Fido). This is part of a solution for the MIPI P1149.7,
* compact JTAG, standard.
*
* This header file will allow other parts of the OS to use the
* interface to write out it's contents for debugging a mobile system.
