 drm/radeon: Fix EEH during kexec

    [ Upstream commit 6f7fe9a93e6c09bf988c5059403f5f88e17e21e6 ]

    During kexec some adapters hit an EEH since they are not properly
    shut down in the radeon_pci_shutdown() function. Adding
    radeon_suspend_kms() fixes this issue.

This commit creates a problem where I can't shut down or restart my system
without pressing the Rest button.  The problem is solved by commenting out the
call to radeon_suspend_kms() in radeon_pci_shutdown.

The gpu hardware is an ATI Radeon HD5770 in a PCI-E slot on an Intel DG41RQ MB.
