This patch adds platform data and partition info for NAND on dm6467 EVM.
Note that the partition layout is dependent on the UBL, U-Boot combination used.
This patch uses partition organization suitable with latest U-Boot of LSP 1.3.
For example, U-Boot environment goes in block 0, UBL resides in block form 1 to
5 and so on.

This check is not really needed. Tghe platform device should exist
regrdless of whether its driver is enabled or not.
