[nrf noup] dts: choose a crypto accelerator for entropy

This is a long-term noup patch because crypto driver support is
NCS-only for both cryptocell and CRACEN.

Set HAS_HW_NRF_CC3XX to be defined in NS build when cryptocell
is accessed through the PSA API.
We need to know which CC3XX features are available.

Set PSA as the entropy source for 54L.

PSA is the only NCS-supported interface to CRACEN.
