dts: nordic: Add DPPIC and IPCT nodes to nRF54H20 EngA

Browse source 
And add the corresponding bindings.

Move alse the already existing bindings for nrf-dppic, nrf-ppi,
and nrf-ipc so they are located together with the new ones and
in more appropriate folders (DPPIC and PPI peripherals are not
related to ARM, and IPC is for sending and receiving events,
not messages, so ipm/ does not seem to be the best fit for it).

description: |
Mapping of IPCT channels that are mapped between two IPCT instances on
separate domains, in which a channel on this IPCT node is considered
the source. This array is then comprised of a 3-integer-wide "unit"
that defines one connection of the mapping. The format of this unit
is <source_channel sink_domain_id sink_channel>. Units are sequential
in the array, therefore requiring the length of this property to be
a factor of 3.
For example, if channel 2 is to be mapped to Radio Core (ID: 3) IPCT
channel 4, then the array "unit" would be <2 NRF_DOMAIN_ID_RADIOCORE 4>
or <2 3 4>.
