[PATCH] W1: possible cleanups

This patch contains the following possible cleanups:
- the following file did't #include the header with the prototypes for
it's global functions:
- w1_int.c
- #if 0 the following unused global function:
- w1_family.c: w1_family_get()
- make the following needlessly global functions static:
- w1_family.c: __w1_family_put()
- w1_io.c: w1_delay()
- w1_io.c: w1_touch_bit()
- w1_io.c: w1_read_8()
- remove the following unused EXPORT_SYMBOL's:
- w1_family.c: w1_family_put
- w1_family.c: w1_family_registered
