video: tegra: dc: add advanced cursor support
Support advanced display cursor for t11x and t14x.
For t14x, window H is set to window mode by default in the sense that
cursor is not necessary for most phones. It can be switched to cursor
mode as below.
echo 0 > /sys/class/graphics/fb0/device/win_h
To switch cursor between normal and legacy mode, user can set flag of
tegra_dc_ext_cursor through the ioctl TEGRA_DC_EXT_SET_CURSOR.
