V4L/DVB (13238): v4l2_subdev: rename tuner s_standby operation to core s_power
Upcoming I2C v4l2_subdev drivers need a way to control the subdevice power state from the core. This use case is already partially covered by the tuner s_standby operation, but no way to explicitly come back from the standby state is available. Rename the tuner s_standby operation to core s_power, and fix tuner drivers accordingly. The tuner core will call s_power(0) instead of s_standby(). No explicit call to s_power(1) is required for tuners as they are supposed to wake up from standby automatically.
