  Remove what appear to be a number of dead kernel config variables,
that apparently have no effect on the build process.

Signed-off-by: Robert P. J. Day <rpjday@mindspring.com>

  whoops, ignore that last patch.  it contained a single line change
to a defconfig file, which is a silly thing to do.  and this patch
adds a few more dead variables.  the dead pool:

USB_SERIAL_SAFE_PADDED
AEDSP16_MPU401
X86_XADD
PARIDE_PARPORT
AIC7XXX_PROBE_EISA_VL
AIC79XX_ENABLE_RD_STRM
SCSI_NCR53C8XX_PROFILE
53C700_IO_MAPPED
ZISOFS_FS
DLCI_COUNT
MOUSE_ATIXL
LCD_DEVICE
VIDEO_VIDEOBUF
USB_USBNET_MII
DEBUG_RWSEMS

  as before, this patch has been compile tested on x86 with "make
allyesconfig".
