hwmon: (lm75) cleanup/reorg

Minor cleanup and reorg of the lm75 code.

 - Kconfig provides a larger list of lm75-compatible chips

 - A top comment now says what the driver does (!) ... as in, just
   what sort of sensor is this??

 - Section comments now delineate the various sections of the driver:
   hwmon attributes, driver binding, register access, module glue.
   One driver binding function moved out of the attribute section,
   as did the driver struct itself.

 - Minor tweaks to legacy probe logic:  correct a comment, and
   remove a pointless variable.

 - Whitespace, linelength, and comment fixes.

This patch should include no functional changes.  It's preparation
for adding new-style (driver model) I2C driver binding.

-          If you say yes here you get support for National Semiconductor LM75
-          sensor chips and clones: Dallas Semiconductor DS75 and DS1775 (in
-          9-bit precision mode), and TelCom (now Microchip) TCN75.

-          The DS75 and DS1775 in 10- to 12-bit precision modes will require
-          a force module parameter. The driver will not handle the extra
-          precision anyhow.
+          If you say yes here you get support for one common type of
+          temperature sensor chip, with models including:
+
+                - Dallas Semiconductor DS75 and DS1775
+                - Maxim MAX6625 and MAX6626

+                - National Semiconductor LM75
+                - NXP's LM75A
+                - ST Microelectronics STDS75
+                - TelCom (now Microchip) TCN75
+                - Texas Instruments TMP100, TMP101, TMP75, TMP175, TMP275
+
+          Most of these chips will require a "force" module parameter.
 
           This driver can also be built as a module.  If so, the module
           will be called lm75.
