Tegra 3 has UART-E exposable via SD card slot which may be
handy for debugging. This change only adds funcmux part, to
use UART-E on the device you additionally would need:
- set stdout-path to serial@70006400 (uarte)
- configure sdmmc1_dat3_py4 and sdmmc1_dat2_py5 pinmux for
  uarte
- disable or remove sdhci@7800000 node
- enable CONFIG_TEGRA_ENABLE_UARTE in defconfig
- set CFG_SYS_NS16550_COM to NV_PA_APB_UARTE_BASE in device
  header

Existing Tegra DSI driver mostly fits T114 apart MIPI calibration
which on T114 has dedicated driver. To resolve this MIPI calibration
logic was split for pre-T114 and T114+ devices.

Consolidate HD headers and place the result into video/tegra20
since it is used only by devices from this directory.

The existing pinctrl driver available for Tegra SOC is well
designed, but it lacks DM support. Let's add a DM compatible
overlay, which allows use of the device tree, along with preserving
backward compatibility with all existing setups and the ability
to use it in SPL board configuration stage.

PLLD2 is a simple clock (controlled by 2 registers) and appears starting
from T30. Primary use of PLLD2 is as main HDMI clock parent.

Adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features
like ganged mode won't work. Driver is heavily based on
mainline Tegra DSI and re-uses much of its features.

Only T30 is supported for now but T20 support can be added
if any supported devices will be found.

Driver is wrapped as panel driver since Tegra DC driver supports
only panel drivers calls.

On popular request make the display driver from T20 work on T30 as
well. Turned out to be quite straight forward. However a few notes
about some things encountered during porting: Of course the T30 device
tree was completely missing host1x as well as PWM support but it turns
out this can simply be copied from T20. The only trouble compiling the
Tegra video driver for T30 had to do with some hard-coded PWM pin
muxing for T20 which is quite ugly anyway. On T30 this gets handled by
a board specific complete pin muxing table. The older Chromium U-Boot
2011.06 which to my knowledge was the only prior attempt at enabling a
display driver for T30 for whatever reason got some clocking stuff
mixed up. Turns out at least for a single display controller T20 and
T30 can be clocked quite similar. Enjoy.

There's no need to replicate the pmu.h header file for every Tegra SoC
generation. Use a single header that is shared across generations.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
