tools headers: Synchronize drm/i915_drm.h

To pick up the changes from these csets:

  bf64e0b0 ("drm/i915: Expand I915_PARAM_HAS_SCHEDULER into a capability bitmask")
  ac14fbd4 ("drm/i915/scheduler: Support user-defined priorities")
  822a4b67 ("drm/i915: Don't use BIT() in UAPI section")
  3fd3a6ff ("drm/i915: Simplify i915_reg_read_ioctl")

None of them affects how the tools are built, this os done just to
silence this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/drm/i915_drm.h' differs from latest version at 'include/uapi/drm/i915_drm.h'
