Log Message:
Put several fixes to ne(4) driver for better 8 bit mode support,
especially on RTL8019AS which is also used for non-ISA local bus of
embedded controllers and some m68k machines like atari and x68k.

 * move RTL8019 probe and attach code from each bus attachment
   to MI ne2000_detect() and ne2000_attach()
 * change a method for backend and attachment to specify 8 bit mode
   to use a new sc->sc_quirk member, instead of sc->sc_dmawidth
 * handle more NE2000 8 bit mode specific settings, including
   bus_space(9) access width and available size of buffer memory
 * add a function to detect NE2000 8 bit mode
   (disabled by default, but enalbed by options NE2000_DETECT_8BIT
    to avoid possible regression on various ISA clones)
 * fix ipkdb attachment accordingly (untested)

Tested on two NE2000 ISA variants (RTL8019AS and another clone named UL0001)
in both 8 bit and 16 bit mode on i386. "Looks good" from nonaka@.
