drm/radeon: replace vmram_mutex with mclk_lock v2
It is a rw_semaphore now and only write locked while changing the clock. Also the lock is renamed to better reflect what it is protecting. v2: Keep the ttm_vm_ops on IGPs Signed-off-by: Christian König <deathsimple@vodafone.de> Reviewed-by: Jerome Glisse <jglisse@redhat.com>
