[PATCH] drm/amd/vcn: fix an error msg on vcn 3.0

[Chen, Guchun]

Hi Tianci,

I think we shall improve the subject a bit like "drm/amdgpu: fix incorrect instance id passing when stopping dpg mode". How do you think?

Regards,
Guchun

Some video card has more than one vcn instance, passing 0 to vcn_v3_0_pause_dpg_mode is incorrect.

Error msg:
Register(1) [mmUVD_POWER_STATUS] failed to reach value
0x00000001 != 0x00000002
