clk: qcom: dispcc-sm6115: remove alpha values from disp_cc_pll0_config

Browse Source 
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.

Despite that enabling alpha mode is not needed for the initial
configuration, the set_rate() op might require that it is enabled
already. In this particular case however, the clk_alpha_pll_set_rate()
function will get reset the ALPHA_EN bit when the PLL's rate changes,
so dropping 'alpha_en_mask' is safe.

No functional changes intended, compile tested only.
