Subject: [PATCH 5/5] clk: qcom: dispcc-sm6115: remove alpha values from
 disp_cc_pll0_config

Since both the 'alpha' and 'alpha_hi' members of the configuration is
initialized (the latter is implicitly) with zero values, the output
rate of the PLL will be the same whether alpha mode is enabled or not.

Remove the initialization of the alpha* members to make it clear that
the alpha mode is not required to get the desired output rate.

No functional changes intended, compile tested only.
