platform/x86: acerhdf: Remove cut-and-paste trap from instructions 

Just like we avoid specifying actual block devices like sda for fdisk
and dd examples, we should not specify specific thermal zones here.

On the platform I was testing on, zone0 was acpitz, and zone1 was for
this acerhdf driver.  Make the printk such that it won't work with a
blind cut-and-paste, and force the user to determine which zone is
correct for this driver.

After loading this driver the BIOS is still in control of the fan.
To let the kernel handle the fan, do:
echo -n enabled > /sys/class/thermal/thermal_zone0/mode
echo -n enabled > /sys/class/thermal/thermal_zoneN/mode
where N=0,1,2... depending on the number of thermal nodes and the
detection order of your particular system. The "type" parameter
in the same node directory will tell you if it is "acerhdf".
For more information about this driver see
