Subject: [PATCH 4.2 043/120] clk: qcom: Set CLK_SET_RATE_PARENT on ce1 clocks

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stephen Boyd <sboyd@...eaurora.org>

commit d7a304e9d018c99dda80f4c16ec0fe817b5be4a1 upstream.

The other ce clocks have the flag set, but ce1 doesn't, so
clk_set_rate() doesn't propagate up the tree to the ce1_src_clk.
Set the flag as this is supported.
