Subject: [PATCH -resend] drm/nouveau/kms/nv50- (gcc13): fix nv50_wndw_new_ prototype

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.

Notes:
    [v2] switch to uint instead of to enum
