1. use the same mutex to serialize the calls from user application.
2. keep iommu attached state when last video is closed,
because the user application may still access the buffer allocated
by v4l2 driver.

when use hdmi-in chip with isp, it needs to pull out/plug in hdmi cable
when stream is on.
many error logs are reported in interrupt function when pull out/plug in
hdmi cable, then the system will be dead.
so we stop isp when too many error logs are reported.

V4L2_BUF_TYPE_META_OUTPUT was added by commit 72148d1a57
("media: v4l: Add support for V4L2_BUF_TYPE_META_OUTPUT") but the patch
missed adding the type to the macro telling whether a given type is an
output type or not. Do that now. Getting this wrong leads to handling the
buffer as a capture buffer in a lot of places.

The V4L2_BUF_TYPE_META_OUTPUT mirrors the V4L2_BUF_TYPE_META_CAPTURE with
the exception that it is an OUTPUT type. The use case for this is to pass
buffers to the device that are not image data but metadata. The formats,
just as the metadata capture formats, are typically device specific and
highly structured.

As gpu clock sources had been changed, the gpu frequencies also
should modifiy.
1. 297MHz is not support and replace it with 300MHz.
2. If enable tow vops, 500MHz is not support,
so remove it from the default table.

Several governors use the user space limits df->min/max_freq to adjust
the target frequency. This is not necessary, since update_devfreq()
already takes care of this. Instead the governor can request the available
min/max frequency by setting the target frequency to DEVFREQ_MIN/MAX_FREQ
and let update_devfreq() take care of any adjustments.
