Subject: [PATCH 06/18] arm64: gicv3: its: Increase FORCE_MAX_ZONEORDER for
 Cavium ThunderX

Patch-mainline: Submitted, http://lists.infradead.org/pipermail/linux-arm-kernel/2015-May/340461.html
References: bsc#1105816

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.

[rric: use ARM64_4K_PAGES since we have now ARM64_16K_PAGES, change order]
