Upstream repo for libhsakmt

[Tom Stellard]

Hi Felix,

What do you think about merging your fxkamd/drm-next-wip into the
master branch of the hsakmt repository of freedesktop[1]?

Fedora is already packaging code from the freedesktop repository,
and it might help to distinguish between the ROCm thunk and the upstream
thunk by keeping them in separate repos.
