drm/amd/display: Fix underflow for fused display pipes case
[Why] Depend on res_pool->res_cap->num_timing_generator to query timing gernerator information, it would case underflow at the fused display pipes case. Due to the res_pool->res_cap->num_timing_generator records default timing generator resource built in driver, not the current chip. [How] Some ASICs would be fused display pipes less than the default setting. In dcnxx_resource_construct function, driver would obatin real timing generator count and store it into res_pool->timing_generator_count.
