<title>drm/amdgpu: Fix the warning info when removing amdgpu device</title>

Actually, the drm_dev_enter in psp_cmd_submit_buf does not
protect anything. If DRM device is unplugged, it will always
check the condition in WARN_ON. So drop drm_dev_enter and
drm_dev_exit in psp_cmd_submit_buf.

When removing amdgpu, the calling order is as follows:
amdgpu_pci_remove
    drm_dev_unplug
    amdgpu_driver_unload_kms
        amdgpu_device_fini_hw

<title>drm/amd: Fix initialization mistake for NBIO 7.3.0</title>

<id>1717cc5f2962a4652c76ed3858b499ccae6c277c</id>
<content type='text'>
The same strapping initialization issue that happened on NBIO 7.5.1
appears to be happening on NBIO 7.3.0.
Apply the same fix to 7.3.0 as well.

Note: This workaround relies upon the integrated GPU being enabled
in BIOS. If the integrated GPU is disabled in BIOS a different
workaround will be required.

v2: use DRM device unplugged flag instead of shutdown flag as the check to

[Why]
Currently, the clk manager matches SocVoltage with voltage from
fused settings (dfPstate clock table). And then corresponding clocks
are selected.

However in certain situations, this leads to clk manager not
including at least one entry with highest supported clock setting.

[How]
Update the clk manager to include at least one entry with highest
supported clock setting.
