ARM: Xen: fix initial build problems
* The XEN_BALLOON code requires the balloon infrastructure that is not getting built on ARM. * The tmem hypercall is not available on ARM * ARMv6 does not support cmpxchg on 16-bit words that are used in the Xen grant table code, so we must ensure that Xen support is only built on ARMv7-only kernels not combined ARMv6/v7 kernels. * sys-hypervisor.c needs to include linux/err.h in order to use the IS_ERR/PTR_ERR/ERR_PTR family of functions.
