[PATCH v3 7/9] clk: qcom: apss-ipq-pll: add support for IPQ8074

Robert Marko

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.

Changes in v2:
* Drop hardcoded compatible check for IPQ6018 to do the PLL config and
utilize match data provided by previous commit
* Add IPQ8074 Alpha PLL config using match data
* Update commit description to reflect changes
