>Description:
Devices attaching to intio(4) are responsible for updating the ia_addr field of their attach args, in order for intioprint to print it.

However, sys/arch/next68k/dev/zsc.c sets ia_addr to the virtual address where the registers are mapped, instead of the physical address.

This causes inconsistency in dmesg:
...
intio0 at mainbus0
esp0 at intio0 addr 0x2114000
zsc0 at intio0 addr 0x3fa000
...
nextdma0 at intio0 addr 0x2000010: channel 0 (scsi)
nextdma1 at intio0 addr 0x2000110: channel 1 (enetx)
nextdma2 at intio0 addr 0x2000150: channel 2 (enetr)
xe0 at intio0 addr 0x2106000
...

and the address will change from one kernel to another.
>How-To-Repeat:
Boot NetBSD/next68k.
>Fix:
In sys/arch/next68k/dev/zs.c zs_match(), set ia_addr to NEXT_P_SCC rather than IIOV(NEXT_P_SCC).
