drm: tegra: Use framebuffer pitch as line stride
Instead of using the stride derived from the display mode, use the pitch
associated with the currently active framebuffer. This fixes a bug where
the LCD display content would be skewed when enabling HDMI with a video
mode different from that of the LCD.
