hwmon: Document which I2C addresses can be probed

Browse source 
Add an item to the checklist when submitting a new hwmon driver: only
some I2C addresses can be probed, others should not for safety
reasons.

* Provide a detect function if and only if a chip can be detected reliably.
* Only the following I2C addresses shall be probed: 0x18-0x1f, 0x28-0x2f,
0x48-0x4f, 0x58, 0x5c, 0x73 and 0x77. Probing other addresses is strongly
discouraged as it is known to cause trouble with other (non-hwmon) I2C
chips. If your chip lives at an address which can't be probed then the
device will have to be instantiated explicitly (which is always better
anyway.)
* Avoid writing to chip registers in the detect function. If you have to write,
only do it after you have already gathered enough data to be certain that the
detection is going to be successful.
