Similarly to am3703, it seems that omap3503 has an IVA control
registers even though the subsystem is non-functional.

This patch sets the OMAP3_HAS_IVA_REGS feature to force
initialization of there registers.

Based in Mark A. Greer's patch
"ARM: OMAP3: Add OMAP3_HAS_IVA_REGS feature".

If you add the flag below, then you probably want to remove it from here, right?
