video: tegra: Fix HDMI mirroring corruption
The new overlay code had this change commented out, because I hadn't
figured out how to get the resolution of the display outside of the fb
driver. This change now grabs it from the h_active and v_active of the
current mode.
Old Change:
video: tegra: Fixed the HDMI corruption issue.
If internal panel has different resolution compared
to HDMI panel, then window attributes are calculated
differently, this causes HDMI panel to show corruption.
This is fixed by checking actual display resolution
while computing window attributes.
