(cherry picked from commit 28901ab621bb56cd2aa9670dc7ce016ba80ec45c)

V4L: cx23885: Bugfix for concurrent use of /dev/video0 and /dev/video1

With the HVR1800, trying to use video0 and video1 simultaneously
caused buffer corruption in the PCIe bridge. This fix reallocates
video1 buffer locations to avoid the issue.
