de0d6dbdbd w1: Add subsystem kernel public interface
Like other subsystems we should be able to define slave devices outside
of the w1 directory. To do this we move public facing interface
definitions to include/linux/w1.h and rename the internal definition
file to w1_internal.h.

As w1_family.h and w1_int.h contained almost entirely public
driver interface definitions we simply removed these files and
moved the remaining definitions into w1_internal.h.

With this we can now start to move slave devices out of w1/slaves and
into the subsystem based on the function they implement, again like
other drivers.

50fa2951bd w1: Organize driver source to natural/common order
Structures and functions should be ordered such that forward declaration
use is minimized.

MODULE_* macros should immediately follow the structures and functions
upon which they act.

Remaining MODULE_* macros should be at the end of the file in
alphabetical order.

939fc83229 w1: add helper macro module_w1_family
The helper macro module_w1_family can be used in module drivers that
only register a w1 driver in their module init functions.  Add this
macro and use it in all applicable drivers.

fa33a65a9c w1: slaves: w1_ds28e04: convert to use w1_family_ops.groups
This moves the sysfs file creation/removal to the w1 core by using the
.groups field, saving code in the slave driver.

8d7bda5188 w1: add family based automatic module loading
This patch allows the 1-wire bus to autoload the corresponding module
for each slave being attached.
This works similar to bluetooth protocols.
