[PATCH] MIPS: Octeon: Add twsi interrupt initialization for OCTEON 3XXX, 5XXX, 63XX

[PATCH] MIPS: Octeon: Add twsi interrupt initialization for OCTEON 3XXX, 5XXX, 63XX

[Eunbong Song]

In octeon_3xxx.dts file, there is a definiton for twsi/twsi2 interrupts.
But there is no code for initialization of this interrupts. This patch adds
code for initialization of twsi interrupts.
