Configure up a Z8530/Z85C30 or Z85230 chip. We check the device
is present, identify the type and then program it to hopefully
keep quite and behave. This matters a lot, a Z8530 in the wrong
state will sometimes get into stupid modes generating 10Khz
interrupt streams and the like.
</p><p>
We set the interrupt handler up to discard any events, in case
we get them during reset or setp.
</p><p>
Return 0 for success, or a negative value indicating the problem
in errno form.
