When multiple instance of iproc-gpio chips are present, a fix up
message[1] is printed during the probe of second and later instances.
This issue is because driver sharing same irq_chip data structure
among multiple instances of driver.
Fix this by allocating irq_chip data structure per instance of
iproc-gpio.
[1] fix up message addressed by this patch
[ 7.862208] gpio gpiochip2: (689d0000.gpio): detected irqchip that
is shared with multiple gpiochips: please fix the driver.

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.
