Matthew N. Dodd 0d6ab4a16a Move the specification of EDGE/LEVEL triggered interrupts to
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.
