    rtw88/rtw89: avoid duplicate top-level directory with debugfs
    
    If people like me having multiple cards in the same system
    creating the debugfs dirctory leads to a panic upon attaching
    the 2nd card due to the duplicate name.
    Rather than using the hard coded driver name, use the device name
    (e.g., rtw880, rtw881, rtw882).
    This solves two issues: it avoids the duplicate name and we get
    individual debugging/statistic information for each card.
