media: sun6i-csi: Move hardware control to the bridge
In order to support the isp workflow, we need to be able to configure
the hardware from the bridge when the capture device is not used.
As a result, move all hardware configuration calls from capture to
the bridge. Only the window configuration part (which is specific
to using capture) remains there.
This effectively opens the way for hooking the bridge to the
isp in the future.
