device: Update Z_DEVICE_INIT_ENTRY_DEFINE to be C++ compatible

tristan-google · kartben · commit aa240e2ecbb3 · 2025-03-13T07:24:25.000+01:00
The `Z_DEVICE_INIT_ENTRY_DEFINE()` macro uses a designated initializer
to define a struct. Ensure all members of `struct init_entry` are
defined in order for C++ compatibility.
