Fix a few things in the aic(4) driver:
- enable 10MHz (fast SCSI) operation on boards that support it. (only
aic6360 boards with fast SCSI enabled can do it)
- bounds check sync periods and offsets passed in from the transport layer
- tell the user which resource allocation failed (for the ISA probe) if we
weren't able to allocate an IRQ, DRQ or I/O port.
