configuration information from a DPT card at a given port.
This is needed by the ISA bus front end (still to come) and the EISA
bus front end (which hasn't ever worked).
- Blow away dpt_eisa.h as the information it contains does not justify
an additional file.
- Convert dpt_eisa.c to use the onboard config instead of trying to
read the EISA configuration registers.

eisa_add_intr() which now takes an additional arguement (one of
EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE).
The flag RR_SHAREABLE has no effect when passed to
bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as
the eisa_alloc_resource() call (bus_alloc_resource method) now deals
with this flag directly, depending on the device ivars.
This change does nothing more than move all the 'shared = inb(foo + iobsse)'
nonesense to the device probe methods rather than the device attach.
Also, print out 'edge' or 'level' in the IRQ announcement message.

functional, but will be in another day or so.
