[PATCH v2 4/4] arm64: dts: qcom: ipq8074: Add CMN PLL

[Robert Marko <robimarko@gmail.com>]

Add the CMN PLL node, it will be used to feed the required fixed clocks
to networking subsystem.

CMN PLL provides bias_pll_cc and bias_pll_nss_noc to GCC.

Signed-off-by: Robert Marko <robimarko@gmail.com>

Changes in v2:
- Drop the _clk suffix from the GCC CMN PLL input names.
