    kernel: add missing kernel config symbol
    
    Bump to 5.10.26 reversed dependencies on IOMMU for CONFIG_VFIO thus
    malta (at least) prompted for this new symbol.
    
    Set it to 'false' in the default config.  rockchip & X86 enable it in
    target specific configs.
    
    Thanks to Tony Ambardar for falling over this one
