sh: intc - remove redundant irq code for sh03, snapgear and titan
This patch removes redundant board specific interrupt code for boards
using sh775x processors and 4 IRQ lines in "Individual Interrupt Mode"
aka IRLM.
Three boards are affected: sh03, snapgear and titan.
The right way to do this is to use cpu specific code provided by intc.
A nice side effect is that sh03 now compiles, board not BROKEN any more.
