Subject: [PATCH v9 0/4] Mediatek MT2701 SCPSYS power domain support 

This series is based on v4.9-rc1 and adds scpsys power domain support
for Mediatek MT2701.

To share the code between MT2701 and MT8173, this patchset also refined
original mtk-scpsys.c to separate common codes and platform codes, so
that mtk-scpsys.c can support new SoCs more easily.

MT8173 and MT2701 scpsys init level are now subsys_init. Please refer to [1]
to see discussion details.

changes since v8:
- Rebase to v4.9-rc1.
- Refine implementation in init_clks() and init_scp().

changes since v7:
- Add clk_id for each scp_domain_data define.
- Minor coding style changes.

changes since v6:
- Minor changes in the dt-binding document.

changes since v5:
- Rebase to v4.6-rc1.
- Add dependent clocks for MFG, ISP, ETH and HIF power domains.
- Add "ethif" as a dependent clock in scpsys dt-binding document.

changes since v4:
- Rebase to v4.5-rc4.
- Remove mtk-scpsys.h and Merge its code into mtk-scpsys.c.
- Add names for every controlling registers and bits.
- Include dt-bindings headers at the beginning of mtk-scpsys.c.
- Sort compatible string in dt-binding documents.

changes since v3:
- Implement MT8173 and MT2701 scpsys drivers in a signle file.
- Remove naming of registers that can't be shared among SoCs.

changes since v2:
- Rebase to mbgg/linux-mediatek v4.4-next/soc [1].
- Remove MTK_SCPSYS_MT8173 and MTK_SCPSYS_MT2701.
- Modify scpsys dt-binding document to support MT2701.

changes since v1:
- Make MTK_SCPSYS in Kconfig invisible from users.
- Add comments for changing scpsys init level to subsys_init.
