Fix concurrent access issue in destroy_buffer_table().
The function is freeing buffers while only holding the
write lock during hash deletion. Other threads could
still be accessing the buffers.
Create a temporary list within the lock and then unmap

Fix v4l2-compliance VIDIOC_G/S_PARM failure.
Below is the function call sequence starting from
ioctl.
doioctl(VIDIOC_G_PARM)
vidioc_g_parm
tegra_channel_g_parm
v4l2_g_parm_cap
v4l2_subdev_call_state_active
v4l2_subdev_call

call_get_frame_interval
check_frame_interval
check_state
In file: v4l2-subdev.c check_state() function
failed at check:
(!state || !state->pads)
Which caused the function to return -EINVAL=-22.
struct v4l2_subdev contain a member
active_state which should be initialized to
overcome the failure. To fill active_state
call v4l2_subdev_init_finalize in
tegracam_v4l2subdev_register().
This failure is seen in K6.8 because in earlier
kernel, v4l2_subdev_call() was called instead of
v4l2_subdev_call_state_active() in
v4l2_g_parm_cap(). And v4l2_subdev doesn't contain
active_state member in earlier kernel.

This change corrects the logic for tracking stats syncpoint
threshold.
In UMD, IspNg sets flag stats_aidx_flag per stats block enabled.
In RCE, this is copied over to the task descriptor as
stats_action_mask.
In Falcon, this mask is used to determine how many times the
stats syncpoint shall be incremented.
This change fixes the logic in isp_capture_request to have the
threshold be based on the same flag from IspNg, by reading it
from the program buffer.

In Linux v6.8, the 'g_frame_interval' and 's_frame_interval' function
pointers were removed from the 'v4l2_subdev_video_ops' structure and
replaced by 'get_frame_interval' and 'set_frame_interval' that were
added to the 'v4l2_subdev_pad_ops' structure.
This change was previously fixed for the Tegra CSI driver by adding the
necessary conftest changes. A new update to the Tegra Cam V4L2 causes
the build to fail for Linux v6.8+ kernels because of the same issue. Fix
up the Tegra Cam V4L2 driver in the same way as the Tegra CSI driver,
but update the name of the conftest test to indicate that this is
applicable for both the 'get_frame_interval' and 'set_frame_interval'
function pointers.

ISP channels are not released cleanly if the IVC send for
CAPTURE_CHANNEL_ISP_RELEASE_REQ were to fail, leaving the
rest of the release steps undone, including unregistering
the capture and control callbacks. This will prevent any
new channel setups, e.g., after an app restart, because
the channel is deemed busy.
Another problem with ISP channel release is that were the
aforementioned IVC sends to fail, the driver will not
attempt an RCE reboot to recover the IVC communications.
Similarly, if the channel reset IVC request fails or
returns an error, the pending capture and program buffers
won't be unpinned and their related waits won't be
completed.
This fix always performs the cleanups regardless of the
fate of the control channel requests.
