[PATCH 2/5] clk: qcom: apps-ipq-pll: drop 'alpha_en_mask' from IPQ5332 PLL config

[Gabor Juhos <j4g8y7@gmail.com>]

Since neither 'alpha' nor 'alpha_hi' is defined in the configuration,
those will be initialized with zero values implicitly. By using zero
alpha values, the output rate of the PLL will be the same whether
alpha mode is enabled or not.

Remove the superfluous initialization of the 'alpha_en_mask' member
to make it clear that enabling alpha mode is not required to get the
desired output rate.

While at it, also add a comment to indicate the frequency the PLL
runs at with the current configuration.

No functional changes, the initial rate of the PLL is the same both
before and after the patch.

Tested on Xiaomi Router BE3600 2.5G (IPQ5312, out-of-tree board).
