[PATCH] Alpha: ISA IRQs fixup for dp264
Basically, this extends original dp264 fixup to all dp264 variations.
Here is one minor change: mask out bits 4-7 of a value assigned by SRM,
because
- newer consoles report ISA IRQs with offset 0xe0;
- even if console IRQ value is bogus, we'll have a value < 16
so it should be harmless as it won't clash with native IRQs.
Particularly this fixes USB interrupt problem on xp1000 and es40.
