The code has been extended to support up to 10 temperature sensors.
The i8k_get_temp_type() calls inside i8k_init_hwmon() have been replaced
with i8k_get_temp() as in some laptop firmwares the related SMM procedure
is not implemented correctly so i8k_get_temp_type() can't be used to
discover temperature sensors.
Changes from v1:
- fix wrong indexes in i8k_is_visible() that were causing unavailable
pwm files to be wrongly exposed by the hwmon interface
