How about remove to call s5p_init_irq() here because All exynos SoCs use
GIC instead of VIC?

NO, the current s5p_init_irq() is not only for VIC but also Timer which is
used on EXYNOS SoCs, I know the name is strange...

I think timer can be selective by MCT on Exynos SoCs.

The patch(ARM: EXYNOS: remove static mapping of PWM memory) is for it.
