video: tegra: dc: Add pixel width setting for even/odd split

Add support of configuring pixel width for symmetric even/odd
ganged mode. The value can be configured by dt property
'nvidia,dsi-even-odd-pixel-width'.
If the panel's dsi-ganged-type is
'TEGRA_DSI_GANGED_SYMMETRIC_EVEN_ODD' and does not have this
dt property, the pixel width is set to 1 by default.
