Subject: [PATCH] [nrf fromlist] dts: nrf5340: cpunet: add hfxo and lfxo nodes
 to soc

The hfxo and lfxo clocks are used by both cpuapp and cpunet cores,
but the hfxo and lfxo nodes are only present in devicetree for the
cpuapp core. This prevents the cpunet build from knowing if there
is an hfxo and/or lfxo present. Therefore add the lfxo and hfxo
clocks to nrf5340_cpunet.dtsi

All boards in tree have both the hfxo and lfxo present. The only
information that needs to be made available to cpunet is the hfxo's
presence and startup time, and lfxo's presence.
