qemuarm: Disable highmem when QB_MACHINE is virt
running ptests on qemuarm returns fails since it finds errors in kernel
logs like below
***********************
Central error: [ 4.338465] pci-host-generic 4010000000.pcie: ECAM ioremap failed
***********************
Since its a 32bit kernel 4010000000 address is truncated to 10000000 and ends up
in conflicts with VIRT_PCIE_MMIO, which ranges from 0x10000000 to 0x3efeffff
This is happening because the linux-yocto kernel is not compiled with
LPAE support, however, virt machine for qemuarm assumes that by default
Should LPAE be enabled by default in kernel config is a separate
question
