Upcoming multi-tce support (H_PUT_TCE_INDIRECT/H_STUFF_TCE hypercalls) will validate TCE (not to have unexpected bits) and IO address (to be within the DMA window boundaries). This introduces helpers to validate TCE and IO address. The helpers are exported as they compile into vmlinux (to work in realmode) and will be used later by KVM kernel module in virtual mode.
