This switches the MSM HDMI code to use GPIO descriptors. Normally we would fetch the GPIOs from the device with the flags GPIOD_IN or GPIOD_OUT_[LOW|HIGH] to set up the lines immediately, but since the code seems eager to actively drive the lines high/low when turning HDMI on and off, we just fetch the GPIOs as-is and keep the code explicitly driving them. The old code would try legacy bindings (GPIOs without any "-gpios" suffix) but this has been moved to the gpiolib as a quirk by the previous patch.

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.
