media: mtk-jpeg: Get rid of mtk_smi_larb_get/put

MediaTek IOMMU has already added device_link between the consumer
and smi-larb device. If the jpg device calls the pm_runtime_get_sync,
the smi-larb's pm_runtime_get_sync also be called automatically.

After removing the larb_get operations, then mtk_jpeg_clk_init is
also unnecessary. Remove it too.
