drm/amd/display: Add is_odm_enabled callback to skip init_odm on active ODM pipes

Browse source

[Why]
dcn10_init_pipes unconditionally calls init_odm on all enabled TGs,
resetting ODM combine state even when it should be preserved.

[How]
Add is_odm_enabled callback to timing_generator_funcs and
guard init_odm to skip when ODM is already active.
