hwmon/smsc47m1: Add support for the LPC47M292

Browse Source 
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.
The 47M15x and 47M192 chips contain a full 'hardware monitoring block'
in addition to the fan monitoring and control. The hardware monitoring
block is not supported by the driver.
The LPC47M15x, LPC47M192 and LPC47M292 chips contain a full 'hardware
monitoring block' in addition to the fan monitoring and control. The
hardware monitoring block is not supported by this driver, use the
smsc47m192 driver for that.
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.
