gpio: rockchip: use devm_platform_ioremap_resource() to map registers

Browse Source 
Currently, the driver retrieves the memory resource with
of_address_to_resource() and maps it with devm_ioremap_resource().

Since the bank device is a platform_device, simplify and modernize the
code by using devm_platform_ioremap_resource(). This also removes the
need for the local struct resource variable.
