ARM: OMAP: Remove IVA IRQ bank

ARM11 can't access the IVA interrupt controller from
IVA slave port.

From Richard Woodruff:

"The 0x40000000 is an IVA-ARM7 local bus address.
The IVA-INTC is NOT accessible through the IVA-L3-Slave Port.
The current TRM does say this directly and indirectly in a few spots and
in figures."
