No attempt has been made to provide proper descriptions for each of
the function arguments throughout the file. Simply demote all
kerneldoc headers to basic function headers.
Fixes the following W=1 kernel build warnings:

Remove MODULE_VERSION(), as it isn't needed at all: the only version
making sense is the kernel version.

It's hard for occasional GPIO code reader/writer to know if values 0/1
equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT to help them out.
NOTE - for gpio-amd-fch and gpio-bd9571mwv:
This commit also changes the return value for direction get to equal 1
for direction INPUT. Prior this commit these drivers might have
returned some other positive value but 1 for INPUT.

Set proper output level base on the argument of direction_output.
Also remove sama5d2_piobu_set_direction() as there is only one caller
now.

PIOBU pins do not lose their voltage during Backup/Self-refresh.
This patch adds a simple GPIO controller for them and a
maintainer for the driver.
This driver adds support for using the pins as GPIO
offering the possibility to read/set the voltage.
