  1. drivers: media: i2c: imx296,imx477: Configure tigger_mode every time 

    Don't assume the camera has been reset each time we start streaming,
but always write registers relating to trigger_mode, even in mode 0.

IMX477: Stop driving XVS on stop streaming, to avoid spurious pulses.

  2. overlays: Add "always-on" parameter to imx477 and imx296 

    Leave the camera's power supplies up, to prevent the camera
clamping its 1.8V digital I/Os to ground. This may be useful
when synchronizing multiple camera systems using XVS or XTRIG.
