AT91 pinctrl deferred probing support is broken if the GPIO devices haven't probed first and set gpio_banks to non-zero. The later condition that only some GPIO devices haven't probed can't actually happen as either all the GPIO devices have probed first or none of them have. Plus the pinctrl driver has already returned -EINVAL, so it's not on the deferred list to retry probing. Fix this by consolidating the checking that all GPIO devices are probed.

README
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.
