From 7bd608426c407a79debea54b2b243950f330c5b8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] 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.
