hwmon: (f75375s) Allow setting up fans with platform_data

Browse Source 
Allow initializing fans on systems where BIOS does not do that by
default.

 - define f75375s_platform_data in new file f75375s.h
 - if platform_data was provided, set fans accordingly in f75375_init()
 - split set_pwm_enable() to a sysfs callback and directly usable
   set_pwm_enable_direct()
