drm/amd/display: amdgpu_dm: add SI support (v4)
[Why]
amdgpu_dm.c requires changes for SI chipsets init and irq handlers registration
[How]
SI support: load_dmcu_fw(), amdgpu_dm_initialize_drm_device(), dm_early_init()
Add DCE6 specific dce60_register_irq_handlers() function
(v1) NOTE: As per Kaveri and older amdgpu.dc=1 kernel cmdline is required
(v2) fix for bc011f9 ("drm/amdgpu: Change SI/CI gfx/sdma/smu init sequence")
remove CHIP_HAINAN support since it does not have physical DCE6 module
(v3) fix vblank irq support for DCE6 using ad hoc dce60_register_irq_handlers()
replicating for vblank irq the behavior of dce110_register_irq_handlers()
as per commit b57de80 ("drm/amd/display: Register on VLBLANK ISR.")
(v4) updated due to following kernel 5.2 commit:
b2fddb13 ("drm/amd/display: Drop underlay plane support")
