of/flattree: Add of_flat_dt_match() helper function
This patch adds of_flat_dt_match() which tests a node for compatibility with a list of values and converts the relevant powerpc platform code to use it. This approach simplifies the board support code a bit. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Reviewed-by: Stephen Neuendorffer <stephen.neuendorffer@xilinx.com>
