    efi: Enable EFI_SET_VIRTUAL_ADDRESS_MAP by default
    
    Many machines fails to boot if this option is disabled.
    It's off by default as it was deemed too risky for being enabled
    by default late in the Xen 4.13 cycle, but found out to be safe.
    As there are no known drawback by having this option on, enable
    it by default.

       Call EFI SetVirtualAddressMap() runtime service to setup memory map for
       further runtime services. According to UEFI spec, it isn't strictly
       necessary, but many UEFI implementations misbehave when this call is
       missing.
