    xen/arm: Remove the parameter "attrindx" in copy_from_paddr
    
    copy_from_paddr is only used with BUFFERABLE, there is some place where
    DEV_SHARED was used by mistake.
    
    The parameter "attrindx" can be safely remove and let copy_from_paddr to map
    every page with BUFFERABLE attribute.
