The variable possible_crtcs is not initialized properly since commit
604be85547ce ("drm/rockchip: Add VOP2 driver"). A first attempt to fix this
issue has been made in commit 368419a2d429 ("drm/rockchip: vop2: initialize
possible_crtcs properly") but turned out to be incomplete. Initialize the
variable with zero to cover all possible paths.
Fixes: 368419a2d429 ("drm/rockchip: vop2: initialize possible_crtcs properly")
