- More Tegra video improvements

Since EDID only indicates supported standard timings, a large table with
detailed timing information is necessary, consuming significant space. To
mitigate this, the table is made configurable via kconfig, allowing it to
be excluded when not needed.

The configuration options CONFIG_VIDCONSOLE_AS_LCD and CONFIG_VIDCONSOLE_AS_
NAME have been marked as obsolete and scheduled for deletion in late 2020.
That's already long overdue and the last remaining consumers of these options
have already migrated to using "vidconsole" in their "stdout" and "stderr"
environment variables, so let's delete these two configuration options.

The reset GPIO signal operates with a low-active logic. The driver

Due to the use of the Tegra DC backlight feature by the HTC ONE X,
backlight requests MUST NOT be made during probe or earlier. This is
because it creates a loop, as the backlight is a DC child.
To mitigate this issue, backlight requests can be made later, once the
backlight is actively used.

This module is a color active matrix LCD module incorporating
Oxide TFT (Thin Film Transistor). It is composed of a color TFT-LCD
panel, driver ICs, a control circuit and power supply circuit, and
a backlight unit. Graphics and texts can be displayed on a 1536x2048
dots panel with (16,777,216) colors by using MIPI DUAL DSI interface,
supplying +3.3V DC supply voltage for TFT-LCD panel driving and
supplying DC supply voltage for LED Backlight.

only register driven backlight control is supported, PWM
driver backlight control may be added later if needed.
