Take advantage of special mask mode by leaving interrupts masked in ISR until
they are serviced. No need to frob IMR.

Enable chaining IRQ only if we're using an IRQ on the slave. Other minor
cleanup.

Grumble. Just set the blasted ICU mode before every read. Also, send the EOIs
to the right port in isa_flushintrs().

Read ISR by default. If DIAGNOSTIC, display ISR and IRR status for stray
interrupts.

isa_discoverintr(): Also check ipending, in case the interrupt is being shared.
Use delay() for timeout rather than timer channel 2.

It does not make sense to mask a fastintr.
