NSS clock controller provides the clocks and resets to the networking
blocks such as PPE (Packet Process Engine) and UNIPHY (PCS) on IPQ5424
devices.
Add support for the compatible string "qcom,ipq5424-nsscc" based on the
existing IPQ9574 NSS clock controller Device Tree binding. Additionally,
update the clock names for PPE and NSS for newer SoC additions like
IPQ5424 to use generic and reusable identifiers "nss" and "ppe" without
the clock rate suffix.
Also add master/slave ids for IPQ5424 networking interfaces, which is
used by nss-ipq5424 driver for providing interconnect services using
icc-clk framework.

The Networking Subsystem (NSS) clock controller acts as both a clock
provider and an interconnect provider. The #interconnect-cells property
is needed in the Device Tree Source (DTS) to ensure that client drivers
such as the PPE driver can correctly acquire ICC clocks from the NSS ICC
provider.
Add the #interconnect-cells property to the IPQ9574 Device Tree binding
example to complete it.
