The Networking Subsystem (NSS) clock controller acts as both a clock
provider and an interconnect provider. The #interconnect-cells property
is mandatory 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.

Although this property is already present in the NSS CC node of the DTS
for CMN PLL for IPQ9574 SoC which is currently supported, it was previously
omitted from the list of required properties in the bindings documentation.
Adding this as a required property is not expected to break the ABI for
currently supported SoC.

Marking #interconnect-cells as required to comply with Device Tree (DT)
binding requirements for interconnect providers.
