I done in config all needed setup to enable LCD
(PHASE and PWM drivers).

Enabling LCD (with different display timimgs) depends now only on DTS/DTB.
The right extension of DTS is not part of patch series.
As I wrote in cover letter:
- To enable functionality see TESTING patch at
   https://github.com/mcerveny/u-boot/tree/simplefb_v3s_v2
(for display 800x480)

or use timmings from previous patch for display (480x472)
