[Freedreno] drm/msm/dpu: Correct dpu encoder spinlock initialization

[Shubhashree Dhar]

dpu encoder spinlock should be initialized during dpu encoder
init instead of dpu encoder setup which is part of commit.
There are chances that vblank control uses the uninitialized
spinlock if not initialized during encoder init.
