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.
