dt-bindings: clock: qcom: Add CMN PLL support for IPQ8074

The CMN PLL block in the IPQ8074 SoC takes 48 MHz as the reference
input clock. Its output clocks are the bias_pll_cc_clk (300 MHz) and
bias_pll_nss_noc_clk (416.5 MHz) clocks used by the networking
subsystem.

Add the related compatible for IPQ8074 to the ipq9574-cmn-pll
generic schema.
