Enable workaround for isapnp assigning already used interrupts to pnp
...
cards by masking them out with a "options ISAPNP_ALLOC_INTR_MASK=..."
in kernel config.

blow up in bus_space_{map,unmap}(). At least one card uses this to `disable'
a logical device.

If ISA DMA is not present in the kernel (i.e. no ISA DMA-using devices
...
configured in), don't call ISA DMA functions to check for DRQs being
free. Just return EINVAL in this case. Fixes PR #6187 , from Herb Peyerl.

Don't reference functions defined in isadma.c if we don't have to,
...
since we might not have any ISA DMA-using devices configured, thus
isadma.c won't be compiled. Fixes a problem reported by Kevin Lahey.
Also, since there are only 8 DMA channels, don't bother checking
DRQs 8 - 15.

DTRT with level and edge interrupts:

- add a type field to the isapnp_pin struct and set to IST_EDGE or
IST_LEVEL depending on the card configuration data.
