arm64: dts: freescale: Add LVDS overlay for TQMa8MPxL
This adds an overlay for the supported LVDS display tianma tm070jvhg33.
The display timings have to be specified explicitly. Using the typical pixel
clock, the LDB clock can not be configured as the 7-fold of that.
By setting pixel clock to 74.25 MHz, LDB can be configured to exactly
519.75 MHz.
