Parameters : r4 = Unit ID
             r5 = previous routine stack pointer

Returns : r2 = 0x00 if unit misc data pointer is invalid (no data stored)
          r2 = 0x01 if unit ID point to a valid Unit misc data pointer
               Store data on previous stack pointer :
                 - 0x00 Unit X mod ((X coord.)*28 + 14)
                 - 0x02 Unit Height data
                 - 0x04 Unit Y mod ((Y coord.)*28 + 14)
