Add experimental support for the it8603e chip (Asus f2a85-m motherboard)
Write only tested for pwmN and pwmN_enable.
Read tested, but the following appear broken:
alarms
fanN_alarm
inN_alarm
inN_max
inN_min
intrusionN_alarm
pwmN_auto_channels_temp
pwmN_freq
temp3_input (there is no 3rd analog temp input to the chip)
