Loop play a video AVC_1080p_24fps_90Mbps_bird90.m2ts met UI
freeze and "rcu stall". Enable CONFIG_DEBUG_SPINLOCK kernel
debug get below call stack, the reason is due to spin_lock
be used in IRQ interrupt and caused deadlock.
8mq board enabled Video overlay feature, there are two fences
enabled: out fence (represent frame on screen) and android out
fence (new added, represent frame off screen). When there are
two fences sync_file_set_fence() will call dma_fence_array_create()
to register irq_dma_fence_array_work(), then gckOS_DestroySignal()
will be called in IRQ which use spin_lock cause deadlock.
Fix solution is use spin_lock_irqsave() instead of spin_lock()
for Database->lock if it is not called in IRQ interrupt.

There is kernel panic when stop android or kill surfaceflinger
after enable framebuffer tile compression on 8mq board.
The root cause of the issue is dcss driver not api to receive
ts fd, gpu driver will set the ts_dma_buf in _SetVidMemMetadata(),
dcss driver get the ts buffer physical address from ts_dma_buf,
when stop android framebuffer and matched ts buffer will free,
previous ts_dma_buf get from ts_fd will be invalid, when dcss
driver use this ts_dma_buf will cause problem. It is a common
issue, if Linux Weston do the similar stop should also meet
the same panic issue.
Keep a reference for ts_dma_buf in _SetVidMemMetadata(),
decrease the reference in _dmabuf_release() can avoid the
panic issue.

Android pass ts_address to dcss to fix kernel panic issue
reported in ticket MA-12928, this fix solution is not formal.
Remove ts_address code to keep align with Linux, if android
still meet panic issue for corner case we need check root
cause and do formal fix.
