dts: nordic: nrf9160: Add missing peripheral nodes

For quite a few peripherals that are currently supported by nrfx HALs
or drivers there are no definitions of corresponding CMSIS-Core
peripheral accessing symbols that would provide their base addresses
in the proper domain (secure or non-secure), accordingly to the build
target. This commits adds devicetree nodes for these peripherals so
that their base addresses can be used in definitions of the accessing
symbols mentioned above.
