[PATCH 7/9] gpio: htc-egpio: use devm_platform_ioremap_resource_nocache()

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

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().
