[PATCH] leds: syscon: Use device property API

[Rosen Penev <rosenp@gmail.com>]

Replace the DT-specific of_property_read_u32() calls and the
dev_of_node()/of_fwnode_handle() roundtrip with their
device/fwnode equivalents. Behaviour is unchanged for device
tree: device_property_read_u32() and dev_fwnode() operate on the
same node, and the fallback from "reg" to "offset" is preserved.

Use dev_fwnode() for init_data.fwnode; unlike a child node from
a scoped iterator, the platform device's own node is held by the
driver core for the device lifetime.
