disable highmem for 32bit arm by default
Since recent qemu, a non-lpae kernel cannot boot a highmem-enabled
virtual machine. A typical failure is:
pci-host-generic 4010000000.pcie: can't claim ECAM area [mem 0x10000000-0x1fffffff]: address conflict with pcie@10000000 [mem 0x10000000-0x3efeffff]
Since the default kernel image is non-lpae, we disable highmem by
default.
