w1: ds250x: Fix build error without CRC16

If CRC16 is not set, building will fails:

drivers/w1/slaves/w1_ds250x.o: In function `w1_ds2505_read_page':
w1_ds250x.c:(.text+0x82f): undefined reference to `crc16'
w1_ds250x.c:(.text+0x90a): undefined reference to `crc16'
w1_ds250x.c:(.text+0x91a): undefined reference to `crc16'
