Suman Anna 4c05160342 ARM: dts: AM3517: Disable absent IPs inherited from OMAP3
AM3517 inherits OMAP3 dts file, but does not have all the IPs
that are present on OMAP3. This patch disables the following
absent IPs for AM3517: Mailbox, IVA, MMU_ISP, MPU_IVA SmartReflex.

A label had to be added for IVA node in omap3.dtsi to be able to
get a reference to the node for disabling.

Otherwise we get the following warnings during booting:
platform iva.2: Cannot lookup hwmod 'iva'
platform 48094000.mailbox: Cannot lookup hwmod 'mailbox'
platform 480bd400.mmu: Cannot lookup hwmod 'mmu_isp'
platform 480c9000.smartreflex: Cannot lookup hwmod 'smartreflex_mpu_iva'
