[PATCH] hwmon: (g762) Initialize fans after configuring clock

[Guenter Roeck]

Adding support for G761 included adding support for an internal clock.
Enabling the internal clock requires setting a bit in the FAN_CMD2
register. This is implemented in g762_fan_init(). However, g762_fan_init()
is called before clock support is selected, and the flag indicating that
the internal clock should be used is not yet set.

Initialize the clock before initializing the fan to solve the problem.
While at it, also add "g7621" to the i2c_device_id array.
