drm/amdgpu: enable DC support for SI parts (v2) 

[Why]
amdgpu_device.c requires changes for SI chipsets support
si.c require changes for Display Manager IP block enabling

[How]
amdgpu_device.c: add SI families in amdgpu_device_asic_has_dc_support()
si.c: changes in si_set_ip_blocks() for Display Manager IP blocks enablement

(v1) NOTE: As per Kaveri and older amdgpu.dc=1 kernel cmdline is required

(v2) fix for bc011f9350 ("drm/amdgpu: Change SI/CI gfx/sdma/smu init sequence")
     remove CHIP_HAINAN support since it does not have physical DCE6 module
