hwmon/smsc47m1: Add support for the LPC47M292

The new SMSC LPC47M292 Super-I/O chip is a bit different from the
previous ones, it supports a 3rd fan, but unfortunately the pin
configuration registers are different.

 The Standard Microsystems Corporation (SMSC) 47M1xx Super I/O chips
 contain monitoring and PWM control circuitry for two fans.

 No documentation is available for the 47M997, but it has the same device
 ID as the 47M15x and 47M192 chips and seems to be compatible.
