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.
