gpio: Rework of_gpiochip_set_names() to use device property accessors In order to use "gpio-line-names" property in systems not having DT as their boot firmware, rework of_gpiochip_set_names() to use device property accessors. This reworked function is placed in a separate file making it clear it deals with universal device properties.

gpio: fix "gpio-line-names" property retrieval commit 822703354774ec935169cbbc8d503236bcb54fda upstream. Following commit 9427ecbed46cc ("gpio: Rework of_gpiochip_set_names() to use device property accessors"), "gpio-line-names" DT property is not retrieved anymore when chip->parent is not set by the driver. This is due to OF based property reads having been replaced by device based property reads. This patch fixes that by making use of fwnode_property_read_string_array() instead of device_property_read_string_array() and handing over either of_fwnode_handle(chip->of_node) or dev_fwnode(chip->parent) to that function.
