UBUNTU: SAUCE: (no-up) arm64: gicv3: its: Increase FORCE_MAX_ZONEORDER for Cavium...

BugLink: http://bugs.launchpad.net/bugs/1558828
In case of ARCH_THUNDER, there is a need to allocate the GICv3 ITS table
which is bigger than the allowed max order. So we are forcing it only in
case of 4KB page size.
