[PATCH] hwmon/ltc2990: Generalise DT to fwnode support

2019-08-16T09:07:31Z

ltc2990 will now use device_property_read_u32_array() instead of
of_property_read_u32_array() - allowing the use of software nodes
via fwnode_create_software_node().

This allows code using i2c_new_device() to specify a default
measurement mode for the LTC2990 via fwnode_create_software_node().
