Fix default_value of ioctl(VIDIOC_QUERYCTRL)(id=V4L2_CID_3A_STATUS)
to AE operating and AWB operating, because both AE and AWB are
automatical adjustment mode by default.
Because the exposure time and ISO sensitivity are adjusted automatically
by default, the default value can not be defined.
So, return the value out of range as the default_value of
ioctl(VIDIOC_QUERYCTRL).
which is useful in the m2m usage scenario, by replacing the first
argument of callback from "struct v4l2_ops_s *" to "struct file *"

Adjust the v4l2 framework to support both capture and v4l2m2m,
and can easily add other v4l2 features.

Because the ratio between API value and ISX019 register value
is 128 : 90 about HUE, some different API values become the
same register value.
So, store the value specified by application in setting,
and return the stored value in getting so that the gotten value
is the same as the setting value by application.
About IMGSENSOR_ID_EXPOSURE_AUTO, IMGSENSOR_ID_ISO_SENSITIVITY_AUTO,
and IMGSENSOR_ID_EXPOSURE_METERING, enumerations are defined.
So, control type should be not integer but integer menu.
About parameter whose register size is less than 4 bytes,
when transfer read value to API parameter, cast appropriately
to avoid the following problems.
- Read value includes garbage value
- Negative value becomes huge positive value
Modify control id definition to avoid duplication even if
the control ids belong to the same control class.
Also, not refer to control class in driver.
The Goldfish FB register should be optimized by considering the need to pass in parameters for base and irq.

To avoid losing the first frame, the set_buf needs to excute first. At the same time, imgdata->start_capture should excuted before the imgsensor->start_capture.

The BIT macro is widely used in NuttX,
and to achieve a unified strategy,
we have placed the implementation of the BIT macro
in bits.h to simplify code implementation.

driver/video: adapting Goldfish FB to VSync optimized FB driver
The circbuf part is implemented by the fb driver, and goldfish needs to
delete the part related to circbuf and adapt to the interface of the fb
driver.

When the upper layer calls goldfish_camera_data_uninit, priv->capture_cb=NULL, but when there is data transmission in goldfish_camera_thread, priv->capture_cb will be called, which will cause a crash.
