[PATCH 08/83] drm/radeon: Add calls to initialize and finalize kfd from radeon

[Oded Gabbay]

The KFD driver should be loaded when the radeon driver is loaded and
should be finalized when the radeon driver is removed.

This patch adds a function call to initialize kfd from radeon_init
and a function call to finalize kfd from radeon_exit.

If the KFD driver is not present in the system, the initialize call
fails and the radeon driver continues normally.

This patch also adds calls to probe, initialize and finalize a kfd device
per radeon device using the kgd-->kfd interface.
