Eero Tamminen 1667b27562 m68k: atari: Fix TT bootup freeze / unexpected (SCU) interrupt messages
[ Upstream commit f70065a9fd ]

Avoid freeze on Atari TT / MegaSTe boot with continuous messages of:

	unexpected interrupt from 112

Which was due to VBL interrupt being enabled in SCU sys mask, but there
being no handler for that any more.

(Bug and fix were first verified on real Atari TT HW by Christian,
 this patch later on in Hatari emulator.)
