This macro simply declares an enum, so drivers might as well declare
it themselves.

Struct i2c_client_address_data only contains one field at this point,
which makes its usefulness questionable. Get rid of it and pass simple
address lists around instead.

The "kind" parameter always has value -1, and nobody is using it any
longer, so we can remove it.

As kind is now hard-coded to -1, there is room for code clean-ups.

What was true of reading the VRM value is also true of writing it: not
being a register value, it doesn't need hardware access, so we don't
need a reference to the i2c client. This allows for a minor code
cleanup. As gcc appears to be smart enough to simplify the generated
code by itself, this cleanup only affects the source code, the
generated binaries are unchanged.

The VRM value is not read from chip registers, so there's no need
to update the device data cache before exporting the VRM value to
user-space.

We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:

in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault

Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.

We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.
