[v4,0/3] Add g_csi_active_lanes for dynamic active lanes

Message

Some MIPI CSI-2 transmitters, such as TC358743 can dynamically change
the number of active data lanes depending on the bandwidth needs for the
selected video format. This patchset adds a subdevice video operation
g_csi_active_lanes() to let the MIPI CSI-2 receiver query the number of
active lanes and change its configuration accordingly.

Changes since v3 [1]:
- Add g_csi_active_lanes() subdevice video operation,
  implement it in tc358743, and use it in imx6-mipi-csi2.
