armvirt: 32: enable CONFIG_ARM_LPAE

Browse Source 
This is required for running armvirt_32 on QEMU 3.0 [1], otherwise the
kernel will emit the following complaint and virtio-net-pci devices will
fail to be initialized

        [    1.124214] OF: PCI: host bridge /pcie@10000000 ranges:
        [    1.125093] OF: PCI:    IO 0x3eff0000..0x3effffff -> 0x00000000

        [    1.129752] pci-host-generic: probe of 4010000000.pcie failed with error -16

Running QEMU with "-M virt,highmem=off" is an option, but "highmem" was only
introduced as a default on flag since QEMU 2.5.0 and QEMU will fail and quit on
encounter of unknown flags
