Many hwmon drivers don't use the id information provided by the old
i2c probe function, and the remainder can easily be adapted to the new
form ("probe_new") by calling i2c_match_id explicitly.
This avoids scanning the identifier tables during probes.
Drivers which didn't use the id are converted as-is; drivers which did
are modified as follows:
* if the information in i2c_client is sufficient, that's used instead
(client->name);
* anything else is handled by calling i2c_match_id() with the same
level of error-handling (if any) as before.
A few drivers aren't included in this patch because they have a
different set of maintainers. They will be covered by other patches.

The HWMON_CHANNEL_INFO macro simplifies the code, reduces the likelihood
of errors, and makes the code easier to read.
The conversion was done automatically with coccinelle. The semantic patch
used to make this change is as follows.

This patch does not introduce functional changes. Many thanks to

Smatch reports:
drivers/hwmon/w83773g.c:105
get_fault() warn: shift has higher precedence than mask
Code analysis shows that the code is indeed wrong.
Fix it, and while we are at it, drop unnecessary typecast.
