Sometimes we have empty banks within the GPIO block. This commit allows proper handling of 0 width GPIO banks. We handle 0 width GPIO banks by incrementing the bank and number of GPIOs, but not initializing them. This will mean a call into the non-existent GPIOs will return an error. Also remove "GPIO registered" dev print. This information is misleading since the incremented banks and gpio_base do not reflect the actual GPIOs that get initialized. We leave this information out since it is already printed with dev_dbg.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
