Subject: [PATCH] clk: qcom: dispcc-sm7150: Fix dispcc_mdss_pclk1_clk_src

From: David Heidelberg <david@...t.cz>

Set CLK_OPS_PARENT_ENABLE to ensure the parent gets prepared and enabled
when switching to it.

Fixes: e3c13e0caa8c ("clk: qcom: dispcc-sm7150: Fix dispcc_mdss_pclk0_clk_src")

I would call it more addition than fix regarding to how the commit is
named, but generally both pclk0 and pclk1 should receive this flag.

Feel free to drop the Fixes tag.
