    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
