xen-tpmfront fails to build on arm64 with the following error:
drivers/char/tpm/xen-tpmfront.c: In function ‘xen_tpmfront_init’:
drivers/char/tpm/xen-tpmfront.c:422:2: error: implicit declaration of function ‘xen_domain’ [-Werror=implicit-function-declaration]
Add include of xen/xen.h to fix this.

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.

All the default durations were being set to 10 minutes which is
way too long for the timeouts. Normal values for the longest
duration are around 5 mins, and short duration ar around .5s.
Further, these are just the default, tpm_get_timeouts will set
them to values from the TPM (or throw an error).
Just remove them.

This is a complete rewrite of the Xen TPM frontend driver, taking
advantage of a simplified frontend/backend interface and adding support
for cancellation and timeouts. The backend for this driver is provided
by a vTPM stub domain using the interface in Xen 4.3.
