Subject: [PATCH] media: iris: Call correct power off callback in cleanup path

Driver implements different callbacks for the power off controller
(.power_off_controller):

 - iris_vpu_power_off_controller,
 - iris_vpu33_power_off_controller,

The generic wrapper for handling power off - iris_vpu_power_off() -
calls them via 'iris_platform_data->vpu_ops', so shall the cleanup code
in iris_vpu_power_on().

This makes also sense if looking at caller of iris_vpu_power_on(), which
unwinds also with the wrapper calling respective platfortm code (unwinds
with iris_vpu_power_off()).

Otherwise power off sequence on the newer VPU3.3 in error path is not
complete.

Fixes: c69df5de4ac3 ("media: platform: qcom/iris: add power_off_controller to vpu_ops")
