[MIPS] Lasat: bring back from the dead
After the common MIPS CPU interrupt controller (for irq0-7) was introduced the Lasat boards didn't get their interrupts right, so nothing worked. The old routines need to be offset by the new 8 hardware interrupts common to all MIPS CPU's. Signed-off-by: Thomas Horsten <thomas@horsten.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
