mac_via: always clear ADB interrupt when switching to A/UX mode
When the NetBSD kernel initialises it can leave the ADB interrupt asserted
depending upon where in the ADB poll cycle the MacOS ADB interrupt handler
is when the NetBSD kernel disables interrupts.
The NetBSD ADB driver uses the ADB interrupt state to determine if the ADB
is busy and refuses to send ADB commands unless it is clear. To ensure that
this doesn't happen, always clear the ADB interrupt when switching to A/UX
mode to ensure that the bus enumeration always occurs.
