Merge patch series "omap3: igep0x00: Fix boot failure and modernize the boards support"

Javier Martinez Canillas <javier@dowhile0.org> says:

Hello,

I noticed that the IGEPv2 board did not boot anymore with mainline U-Boot.
This was caused by a driver change to allocate its platform data before
relocation and U-Boot not having enough pre-relocation heap size for this.

This series fixes this issue and also makes the board support more modern,
by enabling DM for SPL and migrating the IGEP boards to use upstream DTBs.
