Add the seq_file struct forward declaration to intel_display_power.h
fixing the build error below. While at it add the rest of missing
forward declarations/includes to the display power header files.
In file included from <command-line>:
./../drivers/gpu/drm/i915/display/intel_display_power.h:255:70: error: 'struct seq_file'
declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
255 | void intel_display_power_debug(struct drm_i915_private *i915, struct seq_file *m);
