udoo: Switch to SPL support

Browse Source 
Currently we need to build one U-boot image for each of the udoo
variants: quad and dual-lite.

By switching to SPL we can support all two variants with a single binary.

Based on the SPL for wandboard.

Tested with OpenELEC (Open Embedded Linux Entertainment Center)
on both boards.
