ARM: dts: ls1021a-tqmals1021a: Add LVDS overlay for Tianma TM070JVGH33

Browse Source 
This adds an overlay for the supported LVDS display tianma tm070jvhg33.
The on-board RGB-to-LVDS encoder and DCU graphics chain are configured
accordingly. Add power supply as well, which had been missing all the time.
