Final part of the re-organization. Move the `adis16400.h` into
`adis16400.c` since it no longer needs to be shared among other files.

This change does a simple 1-to-1 rename of the adis16400_core.c file. Now
that the `adis16400_buffer.c` file was removed, everything can be moved
into a single driver file.
But first, this rename.
