TCON unit has similar layout and functionality also on newer SoCs. This commit splits out TCON code for easier reuse later.

Signed-off-by: Jernej Skrabec jernej.skrabec@siol.net Acked-by: Maxime Ripard maxime.ripard@free-electrons.com --- Changes in v3: - add acked by tag

Changes in v2: - lcdc conversion to use struct display_timing is done in a new patch - fix issue with lcdc_enable() calls
