drm/amd/powerplay: add check before i2c_add_adapter

Browse source

smu_i2c_eeprom_init may be invoked twice or more
under sroiv mode, while we don't want to add check
if (!amdgpu_sriov_vf) before we invoke smu_i2c_eeprom_init/fini
each time, so we check if i2c adapter is already added
before we invoke i2c_add_adapter
