commit ab3eaa6ea29d846d3beb7dd90dbe0c7e0cea26c4
Author:     Enji Cooper <ngie@FreeBSD.org>

    Add ASMC_DEBUG make option
    
    This allows folks to enable debug statements in asmc(4) using kernel
    configs via the `options ASMC_DEBUG` directive.
    
    While here, remove a duplicate `device vt_efifb` directive in `NOTES`
    as it's already handled in the `GENERIC` config
    
    MFC after:      1 week
    Differential Revision:  https://reviews.freebsd.org/D54511
    
    (cherry picked from commit f224591746bdaf14ad5f63de4738a3146cc2f55f)
