Current amd_fch_gpio_direction_output implementation ignores the value
argument, fix it so direction_output will set proper output level.

The build servers and linux-next are complaining like this:
drivers/gpio/gpio-amd-fch.c: In function 'amd_fch_gpio_probe':
drivers/gpio/gpio-amd-fch.c:164:49: warning: passing argument 2 of
'devm_ioremap_resource' discards 'const' qualifier from pointer
target type [-Wdiscarded-qualifiers]
priv->base = devm_ioremap_resource(&pdev->dev, &amd_fch_gpio_iores);
^~~~~~~~~~~~~~~~~~~
In file included from include/linux/platform_device.h:14, from
drivers/gpio/gpio-amd-fch.c:15:
include/linux/device.h:709:15: note: expected 'struct resource *'
but argument is of type 'const struct resource *'
void __iomem *devm_ioremap_resource(struct device *dev,struct resource *res);
^~~~~~~~~~~~~~~~~~~~~
Let's just remove "const" for now.
It is possible that devm_ioremap_resource() should rather
be constified so we can pass const resources as arguments.
But right now I just want to get rid of this build warning.

GPIO platform driver for the AMD G-series PCH (eg. on GX-412TC)
This driver doesn't registers itself automatically, as it needs to
be provided with platform specific configuration, provided by some
board driver setup code.
Didn't implement oftree probing yet, as it's rarely found on x86.
