    siteinfo: Add mechanism to extend siteinfo information from BSP layer
    
    In order to add a new architecture or sub-architecture to OE, you currently
    need to tweak the table in siteinfo.bbclass. This adds a mechanism so this
    can be done from a BSP layer. It needs a function definition which needs
    a class file but can then be done with something like:
    
    def rp_testfunc2(archinfo, osinfo, targetinfo, d):
        archinfo['testarch'] = "little-endian bit-32"
        osinfo['testos'] = "common-linux"
        targetinfo['mymach-linux'] = "mymach-linux-common"
    
        return archinfo, osinfo, targetinfo
    
    SITEINFO_EXTRA_DATAFUNCS = "rp_testfunc2"
    
    [YOCTO #8554]
