[PATCH] leds: is31fl32xx: Use fwnode/device property APIs

[Rosen Penev <rosenp@gmail.com>]

Convert the DT-specific helpers in is31fl32xx_parse_dt() and
is31fl32xx_parse_child_dt() to their fwnode/device equivalents.
Behaviour is unchanged for device tree: device_property_read_bool(),
device_for_each_child_node_scoped() and device_get_child_node_count()
operate on the same nodes and keep the skip of unavailable children.

Use the %pfwP format specifier in error messages, as child is now a
struct fwnode_handle and %pOF would misread it as a device_node.
