Nouveau - Mar 2023 - [PATCH 5.15 044/145] drm/nouveau/kms/nv50: fix nv50_wndw_new_ prototype

From: Jiri Slaby (SUSE) <jirislaby at kernel.org>

[ Upstream commit 3638a820c5c3b52f327cebb174fd4274bee08aa7 ]

gcc-13 warns about mismatching types for enums. That revealed switched
arguments of nv50_wndw_new_():
  drivers/gpu/drm/nouveau/dispnv50/wndw.c:696:1: error: conflicting types for
'nv50_wndw_new_' due to enum/integer mismatch; have 'int(const
struct nv50_wndw_func *, struct drm_device *, enum drm_plane_type,  const char
*, int,  const u32 *, u32,  enum nv50_disp_interlock_type,  u32,  struct
nv50_wndw **)'
  drivers/gpu/drm/nouveau/dispnv50/wndw.h:36:5: note: previous declaration of
'nv50_wndw_new_' with type 'int(const struct nv50_wndw_func *,
struct drm_device *, enum drm_plane_type,  const char *, int,  const u32 *, enum
nv50_disp_interlock_type,  u32,  u32,  struct nv50_wndw **)'

It can be barely visible, but the declaration says about the parameters
in the middle:
  enum nv50_disp_interlock_type,
  u32 interlock_data,
  u32 heads,

While the definition states differently:
  u32 heads,
  enum nv50_disp_interlock_type interlock_type,
  u32 interlock_data,

Unify/fix the declaration to match the definition.

interlocks")
