ARM: dts: omap3-evm: Add OMAP3530 specific device tree processor data

This commit allows OMAP3530 variants to use common data that is
available in 'omap3-evm-processor-common.dtsi'. It adds proper pinmux
macros for 'omap3_pmx_core2' on OMAP3430. The Micron NAND chip is also
added for the TMDSEVM3530 processor module.
