For there are many hardware need to use, mt8192 is three and mt8195 is
five. Maybe need more to be used in the feature.

Each hardware has independent clk/power/iommu port/irq.
Use component interface in prob to get each component's information.
Just enable the hardware when need to use it, very convenient and
simple.

I found that there are many modules use component to manage hardware
information, such as iommu and drm etc.

Do you have any other suggestion for this architecture?

Thanks
Yunfei Dong
