[PATCH v2 0/4] Add Mediatek MT8173 subsystem clocks support

This patchset is based on 4.1-rc1 plus [1], and contains subsystem
clocks support for Mediatek MT8173.

There are many different implementation suggestions due to each subsystem
HW contains multiple functions, such as clock and reset controllers.

In this patch, I still put subsystem clock implementations in
drivers/clk/mediatek, no mater reset controllers may need to implement
in the same directory in the future. That's because many other vendors
also implement clock and reset controllers in drivers/clk, and it looks
like an acceptible way.

changes since v1:
- Add CA7PLL and CA15PLL as critical clocks.
- Use the same register descriptor for imgsys, vensys and vencltsys.
- Generalize apmixedsys special clocks registration.
