Just as it says: after adding the proper interfaces to gpiolib,
this is no longer needed.

The .direction_output callback should set proper output level.

My left hand merges code to privatize the descriptor handling
while my right hand merges drivers that poke around and
disrespect with the same gpiolib internals.
So let's expose the proper APIs for drivers to ask the gpiolib
core if a line is marked as open drain or open source and
get some order around things so this driver compiles again.

Driver for the GPIO block found in ti's tps65218 pmics.
The device has two GPIOs and one GPO pin which can be configured as follows:
GPIO1:
-general-purpose, open-drain output controlled by GPO1 user bit and/or
sequencer
-DDR3 reset input signal from SOC. Signal is either latched or
passed-trough to GPO2 pin. See below for details.
GPO2:
-general-purpose output controlled by GPO2 user bit
-DDR3 reset output signal. Signal is controlled by GPIO1 and PGOOD.
See below for details.
-Output buffer can be configured as open-drain or push-pull.
GPIO3:
-general-purpose, open-drain output controlled by GPO3 user bit and/or
sequencer
-reset input-signal for DCDC1 and DCDC2.
The input configurations are not meant to be used by the user so the driver
only offers GPOs.
v2: Added request routine that evaluates the fw config flags and removed module
owner
v3: Added .direction_input() routine, and took care of all Linus Walleij
suggestions (clamp to bool, use proper include)
