drm/amd/display: ignore modifiers when checking for format support

Browse source

[Why&How]
There are cases where swizzle modes are set but modifiers arent. For
such a userspace, we need not check modifiers while checking
compatibilty in the drm hook for checking plane format.

Ignore checking modifiers but check the DCN generation for the
supported swizzle mode.
