[PATCH i-g-t 6/8] lib/xe/xe_spin: Move declarations around

[Lucas De Marchi <lucas.demarchi@intel.com>]

xe_spin.h has 3 abstractions:

1) the integration with igt_dummyload
2) xe_spin, the bo to be exec'ed somewhere
3) xe_cork, that resembles more the igt_spin, abstracting the fd, vm,
   bind, etc

Group them so it's easier to understand each one.
