    libpayload: Remove unnecessary keyboard mode setting code
    
    keyboard_init attempts to read the existing mode register, set the
    'XLATE' bit, and write it back. The implementation is buggy because the
    keyboard may be active at the time we read the mode, and we can
    misinterpret scancode data as the reply to our command. It leads to
    problems where the KB gets disabled in firmware.
    
    In fact, setting the 'XLATE' bit is completely unnecessary, even if we
    desire QEMU keyboard support. We already set this bit when we initialize
    the keyboard in pc_keyboard_init. Basically, this code does nothing
    (or worse), so just remove it.
