drm/amd/display: add additional refresh rate conditions for SubVP cases

Browse Source 
[Why]
Want to further constrain these refresh rate conditions for SubVP:
- SubVP + SubVP: either both <= 120Hz or both between 120-165Hz
- SubVP + DRR: SubVP <= 120Hz
- SubVP + VBlank: SubVP <= 120Hz

[How]
Add constraints in subvp_subvp_admissable(),
dcn32_subvp_drr_admissable() and dcn32_subvp_vblank_admissable()
