drm/tegra: Fix genpd support for Linux v6.13

Browse Source 
In Linux v6.13, commit d6caca30a548 ("OPP: Drop redundant
*_opp_attach|detach_genpd()") removed devm_pm_opp_attach_genpd(). This
has been replaced by devm_pm_domain_attach_list(). Use conftest to
detect the presence of devm_pm_domain_attach_list() and update the Tegra
DRM driver accordingly.
