The IP Core Z025 and Z057 have a register where the amount of UART ports is specified. Such register is located at offset 0x40. This patch fixes the way the UART ports is calculated by reading the actual register. Additionally a refactor was needed to achieve this so we can keep track of the UART line and its offset which also improves the remove callback.

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.
