The atomic debugfs stuff gets created in drm_dev_alloc()
but this gets called before we've enumerated all of our
IPs, so move the DRIVER_ATOMIC flag setting to fix that.

Since DRIVER_ATOMIC is a driver flag it's currently global
to the driver so setting it affects all GPUs driven by the
driver.  Unfortunately, not all GPUs support atomic.  Warn
the user if that is the case.

This is the same as our current behavior, but at least the
atomic debugfs stuff gets created now.

The preinstall callback didn't do anything because not all
of the IPs were initialized when it was called.

Move the postinstall setup into sequence in the driver.

The uninstall callback disabled all interrupt source, but
it got called too late in the driver sequence and caused problems
with IPs who already freed the relevant data structures.  Move
the call into the right place in the driver sequence.

This moves and renames the AMDGPU scheduler to a common location in DRM
in order to facilitate re-use by other drivers. This is mostly a straight
forward rename with no code changes.

One notable exception is the function to_drm_sched_fence(), which is no
longer a inline header function to avoid the need to export the
drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.

SRIOV doesn't implement PMC capability of PCIe, so it can't update
power state by reading PMC register.

Currently, amdgpu driver doesn't disable pci device when removing
driver, the enable_cnt of pci device will not be decrease to 0.
When reloading driver, pci_enable_device will do nothing as
enable_cnt is not zero. And power state will not be updated as PMC
is not support.
So current_state of pci device is not D0 state and pci_enable_msi
return fail.

Add pci_disable_device when remmoving driver to fix the issue.
