Douglas Anderson 712908fec2 CHROMIUM: drm: rockchip: Add a timeout in dmc_notify()
There's at least one instance where the completion waited on in
dmc_notify() never happened.  This happened because the mode stored in
"vop->crtc.hwmode" didn't match the current hardware mode while we're in
the middle of a resolution change.

We've got a fix for the above problem (see
CL:Ic78730293ba2d8d6c27ee833d27c519b59c6b717) but it also seems wise to
add a timeout here for extra safety.

BUG=chrome-os-partner:48332
TEST=Without above CL see printout; can't reproduce hang anymore.
