[MIPS] DECstation: Fix irq handling
When I post a patch (commit f431baa55abf8adeed0c718b51deacbc151f58f1), I just tried to not change behavior of existing codes, but it seems dec/int-handler.S had been broken since its previous commit 937a801576f954bd030d7c4a5a94571710d87c0b. The caller of plat_irq_dispatch do setup/restore TI_REGS($28), so dec's plat_irq_dispatch should not do it, and there is no need to adjust RA.
