[PATCH v3 5/9] clk: qcom: apss-ipq-pll: use OF match data for Alpha PLL config

[Robert Marko <robimarko@gmail.com>]

Convert the driver to use OF match data for providing the Alpha PLL config
per compatible.
This is required for IPQ8074 support since it uses a different Alpha PLL
config.

While we are here rename "ipq_pll_config" to "ipq6018_pll_config" to make
it clear that it is for IPQ6018 only.
