Mark function radeon_bo_clear_va() as static in
drm/radeon/radeon_object.c because it is not used outside this file.

This eliminates the following warning in drm/radeon/radeon_object.c:

Fill in asic family specific versions rather than
using the generic version.  This lets us handle asic
specific differences more easily.  In this case, we
disable sw swapping of the rtpr writeback value on
r6xx+ since the hw does it for us.  Fixes bogus
rptr readback on BE systems.

We need more control over the ordering of dpm init with
respect to the rest of the asic.  Specifically, the SMC
has to be initialized before the rlc and cg/pg.  The pm
code currently initializes late in the driver, but we need
it to happen much earlier so move pm handling into the asic
specific callbacks.

This makes dpm more reliable and makes clockgating work
properly on CIK parts and should help on SI parts as well.

Right now it's called right after enable, but after

This is just used for a debugfs file, and we can easily reconstruct
this number by just walking the list twice. Which isn't really bad for
a debugfs file anyway.

So let's rip this out.

There's the other issue that the dev->vmalist itself is a bit useless,
since that can be reconstructed with all the memory mapping
information from proc. But remove that is a different topic entirely.

It's racy, and it's only used in debugfs. There are simpler ways to

Now dev->ioctl_count tries to prevent the device from disappearing if

hopelessly racy and broken.

But luckily the vfs already takes care of this. So we can just rip it
out.
