[PATCH v4 3/4] arm64: dts: freescale: add LVDS overlays for TQMa8MPxS

[Alexander Stein]

From: Paul Gerber <paul.gerber@xxxxxxxxxxxx>

This adds overlays for the supported LVDS display tianma tm070jvhg33
for both LVDS channels.

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.
