drivers: camera: Fix power on function calls

Since sensor and forcuser has the same V4L2 group id,
when device s_power callback is called, the power_on
function of sensor and foucser will both be called,
even though only one of them needs to be powered on.

Switched to subdev s_power call to power on either
sensor or focuser, instead of both of them.
