gpio: amd-fch: Drop const from resource

Browse Source 
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.
