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

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.
