dt: add helper function to read u32 arrays
Rework of_property_read_u32 to read an array of values. Then of_property_read_u32 becomes an inline with array size of 1. Also make struct device_node ptr const. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
