After the chipidea driver introduce extcon for id and vbus, it's able
to wakeup from another irq source, in case the system with extcon ID
cable, wakeup from usb ID cable and device removal, the usb device
disconnect irq may come firstly before the extcon notifier while system
resume, so we will get 2 "wakeup" irq, one for usb device disconnect;
and one for extcon ID cable change(real wakeup event), current driver
treat them as 2 successive wakeup irq so can't handle it correctly, then
finially the usb irq can't be enabled. This patch adds a check to bypass
further usb events before controller resume finished to fix it.

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.
