[ 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.
