[U-Boot] [PATCH V3 4/5] arm: da850-evm: Enable MTD Parts

[Adam Ford]

There is a discrepency between U-Boot and Linux on the partition map.
This enabes the MTD parts to pass MTD partition information from U-Boot to
Linux.  Linux already has a pending patch to enable MTD PARTS in
davinci_all_defconfig
