mpfs_gpio_direction_output() actually sets the line to input mode.
Use the correct register settings for output mode so that this function
actually works as intended.
This was a copy-paste mistake made when converting to regmap during the
driver submission process. It went unnoticed because my test for output
mode is toggling LEDs on an Icicle kit which functions with the
incorrect code. The internal reporter has yet to test the patch, but on
their system the incorrect setting may be the reason for failures to
drive the GPIO lines on the BeagleV-fire board.

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 reStructuredText 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.
