[PATCH 03/10] device property: Add fwnode_property_read_int_array()

[Remo Senekowitsch <remo@buenzli.dev>]

The rust bindings for reading device properties has a single
implementation supporting differing sizes of integers. The fwnode C API
already has a similar interface, but it is not exposed with the
fwnode_property_ API. Add the fwnode_property_read_int_array() wrapper.
