1292c12959 arm/dt: tegra: Fix SDHCI nodes to match board files
Mark any SDHCI controllers that aren't registered by the board files as
disabled in the device-tree files.

In practice, these controllers:

* Have nothing hooked up to them at all, or
* For ports intended for SDIO usage, the drivers for anything that might
  be attached are not in the device-tree yet. If/when drivers appear, the
  SD/MMC port can be re-enabled.

The only possible exception is TrimSlice's mico SD slot, but that wasn't
enabled in the board files before anyway, and doesn't work when all the
SDHCI controllers are enabled anyway.

31c1ec9282 arm/dt: tegra: Fix serial nodes to match board files
Mark any serial ports that aren't registered by the board files as disabled
in the device-tree files.

In practice, none of the now-disabled ports ended up succeeding device
probing because of the missing clock-frequency property. However,
explicitly marking the devices disabled has the advantage of squashing
the dev_warn() the failed probe causes, and documenting that we intend
the port not to be used, rather than accidentally left out the property.

88950f3b6d arm/dt: tegra: Fix I2C nodes to match board files
With board files, all I2C busses run at 400KHz. Fix the device-tree
to be consistent with this. It's possible this is incorrect, but at
least it keeps the board files and device-tree consistent.

Also, disable any I2C controllers that the board files don't register,
also for consistency.

492f204da8 arm/dt: tegra: Remove /chosen node
The command-lines present in the existing /chosen node are not necessarily
correct for all users. Ideally, we should simply use the command-line
supplied by the boot-loader.

In fact, using the boot-loader's cmdline is quite easy; either the
bootloader fully supports DT, in which case it can modify the DT passed
to the kernel to include its command-line, or CONFIG_APPENDED_DTB can
be used in conjunction with CONFIG_ARM_ATAG_DTB_COMPAT, and the kernel
will substitute the bootloader's command-line into the DT.

5a85426506 arm/dt: tegra: Remove /memreserve/ from device-tree files
There are no drivers in the kernel at present which can make use of the
memory reserved by /memreserve/, so there is no point reserving it. Remove
/memreserve/ to allow the user more memory. It's also unclear whether any
future driver would actually require /memreserve/, or allocate memory
through some other mechanism.

c406eeb3aa arm/dt: Fix ventana SDHCI power-gpios
Ventana uses the same SDHCI GPIOs as Seaboard; PI6 (70) is the power GPIO
for the SD port, and there is no power GPIO for the MMC chip.
