drm/ttm: move memory accounting into vmwgfx v4
This is just another feature which is only used by VMWGFX, so move it into the driver instead. I've tried to add the accounting sysfs file to the kobject of the drm minor, but I'm not 100% sure if this works as expected. v2: fix typo in KFD and avoid 64bit divide v3: fix init order in VMWGFX v4: use pdev sysfs reference instead of drm Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Zack Rusin <zackr@vmware.com> (v3) Tested-by: Nirmoy Das <nirmoy.das@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210208133226.36955-2-christian.koenig@amd.com
