Subject: [PATCH 0/2] clk: Fix CLK_OPS_PARENT_ENABLE and runtime PM

Hi Mike, Stephen,

Here are a couple fixes for the clk core. They are unrelated but overlap
in diff context, so I'm sending them together.

Patch 1 makes the clk core honor CLK_OPS_PARENT_ENABLE for clk gate ops.
Without this, dumping clk_summary on the MT8192 would cause the system
to hang.

Patch 2 reorders the runtime PM call in clk_core_unprepare() to match
the order described in its original commit, and the opposite of that
in clk_core_prepare().

Regards
ChenYu
