The NSS clock controller on the IPQ5424 SoC provides clocks and resets
to the networking related hardware blocks such as the Packet Processing
Engine (PPE) and UNIPHY (PCS). Its parent clocks are sourced from the
GCC, CMN PLL, and UNIPHY blocks.

Additionally, register the gpll0_out_aux GCC clock, which serves as one
of the parent clocks for some of the NSS clocks.

The NSS NoC clocks are also enabled to use the icc-clk framework, enabling
the creation of interconnect paths for the network subsystem’s connections
with these NoCs.

The NSS clock controller receives its input clocks from the CMN PLL outputs.
The related patch series which adds support for IPQ5424 SoC in the CMN PLL
driver is listed below.
