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".
