drm/tegra: dc: Remove redundant spinlock
The spinlock is only used to serialize accesses to the DC_CMD_INT_MASK register. However, this register is accesses either with interrupts masked (in tegra_crtc_atomic_enable()) or protected by the vbl_lock and vblank_time_lock spinlocks of the DRM device. Therefore, these accesses don't need any extra serialization and the lock can be removed. Signed-off-by: Thierry Reding <treding@nvidia.com>
