This patch will modify a pair of functions for pcie port wreg/rreg.
AMD GPU have had an independent NBIO block from SOC15 arch.
If the dirver wants to read/write the address space of the pcie devices,
it has to go through the NBIO block.
This patch will move the pcie port wreg/rreg functions to
"amdgpu_device.c", so that to reuse the functions on the
future GPU ASICs.

I met a bug recently and the kernel log:

[  330.171875] radeon 0000:03:00.0: couldn't schedule ib
[  330.175781] [drm:radeon_uvd_suspend [radeon]] *ERROR* Error destroying UVD (-22)!

In radeon drivers, using UVD suspend is as follows:

if (rdev->has_uvd) {
        uvd_v1_0_fini(rdev);
        radeon_uvd_suspend(rdev);
}

In radeon_ib_schedule function, we check the 'ring->ready' state,
but in uvd_v1_0_fini funciton, we've cleared the ready state.
So, just modify the suspend code flow to fix error.

[Why]
For allow eDP hot-plug feature, the stream signal may change to VIRTUAL
when plug-out and back to eDP when plug-in. OS will still setPathMode
with same timing for each plugging, but eDP gets no stream update as we
don't check signal type changing back as keeping it VIRTUAL. It's also
unsafe for future cases that stream signal is switched with same timing.

[How]
Check stream signal type change include previous HDMI signal case.

eb4fd29a ("drm/amdgpu: bind to any 0x1002 PCI diplay class device") added
generic bindings to amdgpu so that that it binds to all display class devices
with VID 0x1002 and then rejects those in amdgpu_pci_probe.

Unfortunately it reuses a driver_data value of 0 to detect those new bindings,
which is already used to denote CHIP_TAHITI ASICs.

The driver_data value given to those new bindings was changed in
dd0761fd24ea1 ("drm/amdgpu: set CHIP_IP_DISCOVERY as the asic type by default")
to CHIP_IP_DISCOVERY (=36), but it seems that the check in amdgpu_pci_probe
was forgotten to be changed. Therefore, it still rejects Tahiti GPUs.
