arm/common/vic.c doesnt have a set_type callback. We have some edge
triggered interrupts as wakeup interrupts and need the PENDING flag in
the descriptor set when disabled. Can we move msm_irq_set_type() to
- the register map is different between msm's vic and the common one.
- the common one uses some PL190 registers, not sure what that is. The
VIC can operate in few different modes, perhaps it refers to vectored
mode as opposed to non vectored mode, msm uses the non vectored mode.
- vic_init2() seems like it is initializing a cascaded interrupt
controller. msm doesnt use cascaded vics.
I dont think msm can move to using the common vic.c.
