We have standard drivers for panels and backlights which can do most of the
work for us. Move the tegra20 LCD driver over to use those instead of custom
code.
This patch includes device tree changes for the nvidia boards. I have only
been able to test seaboard. If this patch is applied, these boards will
also need to be synced with the kernel, and updated to use display-timings:
- colibri
- medcom-wide
- paz00
- tec

Sync everything except the display panel, which will come in a future patch.
One USB port is left disabled since we don't want to support it in U-Boot.

This prevents the following boot-time message on any board where only the
first DC is in use, yet the DC's DT node is enabled:
stdio_add_devices: Video device failed (ret=-22)
(This happens on at least Harmony, Ventana, and likely any other Tegra20
board with display enabled other than Seaboard).
The Tegra DC's DT node represents a display controller. It may itself
drive an integrated RGB display output, or be used by some other display
controller such as HDMI. For this reason the DC node itself is not
enabled/disabled in DT; the DC itself is considered a shared resource, not
the final (board-specific) display output. The node should instantiate a
display output driver only if the rgb subnode is enabled. Other output
drivers are free to use the DC if they are enabled and their DT node
references the DC's DT node. Adapt the Tegra display drivers' bind()
routine to only bind to the DC's DT node if the RGB subnode is enabled.
Now that the display driver does the right thing, remove the workaround
for this issue from Seaboard's DT file.

Use the driver-model PWM driver in preference to the old code.

Move this driver over to use driver model. This involves rearranging the
code somewhat. The effect is that everything is run from the probe() method.
Boards which use this are fixed up, but only seaboard is tested.

This file has changed quite a bit since it was set up. Sync it back with
Linux v4.4. Adjust the users slightly to cope with the changes:
- the host1x node is now called host1x@50000000
- we need a clocks node to provide the clk32k_in phandle
- active usb nodes need status = "okay"
- active i2c nodes need status = "okay"

Some Tegra device tree files do not include information about the serial
ports. Add this and also add information about the input clock speed.
The console alias needs to be set up to indicate which port is used for
the console.
Also add a binding file since this is missing.
Series-changes; 5
- Add full serial port nodes from Linux tree (commit fc9d4dbe)
- Use /chosen/stdout-path instead of /aliases/console to specify the console

Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.
I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.
For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.
This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.
