Finn Thain 3eccf76b57 m68k: mac: Fix reboot hang on Mac IIci
[ Upstream commit 265a3b322d ]

Calling mac_reset() on a Mac IIci does reset the system, but what
follows is a POST failure that requires a manual reset to resolve.
Avoid that by using the 68030 asm implementation instead of the C
implementation.

Apparently the SE/30 has a similar problem as it has used the asm
implementation since before git. This patch extends that solution to
other systems with a similar ROM.

After this patch, the only systems still using the C implementation are
68040 systems where adb_type is either MAC_ADB_IOP or MAC_ADB_II. This
implies a 1 MiB Quadra ROM.

This now includes the Quadra 900/950, which previously fell through to
the "should never get here" catch-all.
