Advertise the maximum offset the .adjphase callback is capable of supporting in nanoseconds for IDT devices. Refactor the negation of the offset stored in the register to be after the boundary check of the offset value rather than before. Boundary check based on the intended value rather than its device-specific representation. Depend on ptp_clock_adjtime for handling out-of-range offsets. ptp_clock_adjtime returns -ERANGE instead of clamping out-of-range offsets.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
