pathres: consistently encode unit address on 64bit target 

This change fixes node unit address matching on arch
where cell is not 4 byte integer (tested with sparc64.)

Since we encode "reg" property chunks with encode-int
we need to use the same encoding while preparing unit
phys addr for comparison at path resolution time.

- (exact-match): calculate phys addr length using 4 byte
  member encoding with /l* not cells

- find-child: encode phys addr components similar to
  encode-int with 4 byte stores
