Register each hardware(subdev) as platform device used to manage each hardware information which includes irq/power/clk. The hardware includes LAT0, LAT1 and CORE. And call of_platform_populate in main device.

Using subdev_bitmap to record whether each device is register done. Then check whether all subdev are register done before open main device.

Use the dma_set_mask_and_coherent helper to set vdec DMA bit mask to support 34bits iova space(16GB) that the mt8192 iommu HW support.

Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G, regarding which iova range VDEC actually locate, it depends on the dma-ranges property of vdec dtsi node.

There are only two lines in mtk_vcodec_release_dec_pm, using pm_runtime_disable and put_device instead directly.

Move pm_runtime_enable outside mtk_vcodec_init_dec_pm to symmetry with pm_runtime_disable, after that, rename mtk_vcodec_init_dec_pm to *_clk since it only has clock operations now.
