[PATCH 8/9] gpio: xgene: use devm_platform_ioremap_resource_nocache()

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszew...@baylibre.com>

Use the new devm_platform_ioremap_resource_nocache() helper for memory
range mapping instead of devm_ioremap_nocache() combined with a call to
platform_get_resource().
