[RESEND,v3,0/4] rockchip: add GATE_LINK

Message

Recent Rockchip SoCs have a new hardware block called Native Interface
Unit (NIU), which gates clocks to devices behind them. These effectively
need two parent clocks.
Use GATE_LINK to handle this.

change in V3:
[PATCH v3 1/4]: new, export clk_gate_endisable for PATCH2.
[PATCH v3 2/4]: reuse clk_gate_endisable and clk_gate_is_enabled.
                add prepare and unprepare ops.
[PATCH v3 3/4]: No change
[PATCH v3 4/4]: reword commit message

change in V2:
[PATCH v2 1/3]: fix reported warnings
[PATCH v2 2/3]: Bindings submit independent patches
[PATCH v2 3/3]: fix reported warnings
