media: i2c: imx283: Enter full standby when stopping streaming

Browse Source 
Use IMX283_STANDBY (bit 0) instead of IMX283_STBLOGIC (bit 1) when
stopping streaming. STBLOGIC only puts the sensor logic into standby but
leaves the MIPI interface (along with other components) in an
indeterminate state.

This (presumably) causes the CSI receiver (e.g. Raspberry Pi's CFE) to
miss the LP-11 to HS transition when streaming restarts, resulting in a
hang of 10+ seconds. The issue is most visible when immediately
restarting a full-resolution stream after stopping a 3x3 binned one, so
that runtime suspend hasn't yet been triggered.

Writing IMX283_STANDBY puts the entire sensor into standby. The
imx283_standby_cancel() sequence already handles the full wakeup from
this suspended state.
