[v2,0/2] hwmon: (sch5627) Add pwmX_auto_channels_temp attributes

Message

After doing some research, i found out that Fujitsu's hardware
mointoring solution inside the SCH5627 exports data thru
registers 0xA0 - 0xA3 regarding the mapping between temperature
sensors and fans. If those registers are set to 0, the fans
are forced to full speed.
The first patch adds support for pwmX_auto_channels_temp
attributes to the hwmon core, while the second patch does
extend the sch5627 driver.

Both patches have been tested on a Fujitsu Esprimo P720.

Changes in v2:
- acquire mutex before doing register reads/writes
