Utilize the newly fixed up DT bindings to get the tx2 and rx2 register regions for the second lane of dual-lane PHYs. Before this change, the driver was simply using lane one's register region and adding 0x400, which reached well beyond the DT-specified register allocation. This would have been a crash were it not for the page size on ARM64. Fix the driver not to rely on the magic of virtual memory by using the newly specified DT register regions for tx2 and rx2. In order to support existing device trees, this change also contains a fallback mode for when those new register regions don't exist, which reverts to the original behavior of overreaching and prints a complaint.

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.
