From e0a711bd88ba98f6ab5118d248ec84fcf495d313 Mon Sep 17 00:00:00 2001

Subject: [PATCH] clk: qcom: apss-ipq-pll: add support for IPQ8074
Add support for IPQ8074 since it uses the same PLL setup, however it uses
slightly different Alpha PLL config.
Alpha PLL config was obtained by dumping PLL registers from a running
device.
