[PATCH] crc16: remove w1 specific comments.

Remove w1 comments from crc16.h and move
specific constants into w1_ds2433.c where they are used.
Replace %d with %zd.

 /*
  *     crc16.h - CRC-16 routine

- * Implements the standard CRC-16, as used with 1-wire devices:
+ * Implements the standard CRC-16:
  *   Width 16
  *   Poly  0x8005 (x^16 + x^15 + x^2 + 1)
  *   Init  0
  *
- * For 1-wire devices, the CRC is stored inverted, LSB-first
- *
- * Example buffer with the CRC attached:
- *   31 32 33 34 35 36 37 38 39 C2 44
- *
- * The CRC over a buffer with the CRC attached is 0xB001.
- * So, if (crc16(0, buf, size) == 0xB001) then the buffer is valid.
- *
