[PATCH] Add a hack to initialize TDA pins

[Vijay Kumar Banerjee]

Hello all,

This following patch uses a device tree overlay to enable the
initialization of only the required pins, to avoid conflict with
other drivers in the BSP. However, this might not be the best
solution and also it increases the dependency on the device tree
overlay. I have checked this to be working on target and have
gotten output from framebuffer on screen.

The overlay can be seen here: https://gist.github.com/thelunatic/dd274cb423ea6d3bfbf4c6b06496126c

I seek some advice/discussion on this approach and if it's alright
to do it with device tree overlay.

Since we already have the i2c driver using a device tree overlay
this also brings up the discussion of a place to keep the overlays
somewhere in the repository. What can be a good place for that?

Thank you,
Vijay
