[PATCH] hwmon: tag super-i/o find functions __init

Super-I/O find functions in hardware monitoring drivers can be tagged
__init as they are only called from functions themselves tagged __init.
Two of them (smsc47b397 and w83627ehf) already do, but the other four
of them (it87, pc87360, smsc47m1 and w83627hf) did not.

This saves a few bytes of memory after the drivers are loaded, 192 in
the case of the it87 driver.
