tpm: xen-tpmfront: Remove the locality sysfs attribute
Upon deeper review it was agreed to remove the driver-unique
'locality' sysfs attribute before it is present in a released
kernel.
The attribute was introduced in e2683957fb268c6b29316fd9e7191e13239a30a5
during the 3.12 merge window, so this patch needs to go in before
3.12 is released.
The hope is to have a well defined locality API that all the other
locality aware drivers can use, perhaps in 3.13.
