tegra: fdt: Ensure that the console UART is enabled

Many tegra boards have the console UART node disabled. With livetree this
prevents serial from working since it does not 'force' the console to be
bound. Updates the affected boards to fix this error.

The boards were checked with:

for b in $(grep tegra boards.cfg |grep -v integrator | \
awk '{print $7}' | sort); do
echo $b;
fdtgrep -c nvidia,tegra20-uart b/$b/u-boot.dtb |grep okay;

ARM: tegra: fix USB controller aliases

Some boards have a different set of USB controllers enabled in DT than
the set referenced by /alias entries. This patch fixes that. For
example, this avoids the following message while booting on Ventana,
which is caused by the fact that the USB0 controller had no alias, and
defaulted to wanting a sequence number of 0, which was later explicitly
requested by the alias for USB controller 2.

USB2: Device 'usb@c5008000': seq 0 is in use by 'usb@c5000000'

This didn't affect USB operation in any way though.

Related, there's no need for the USB controller aliases to have an order
that's different from the HW order, so re-order any aliases to match the
HW ordering. This has the benefit that since USB controller 0 is the only
one that supports device-mode in HW, and U-Boot only supports enabling
device move on controller 0, there's now good synergy in the ordering! For
Tegra20, that's not relevant at present since USB device mode doesn't work
correctly on that SoC, but it will save some head-scratching later.

This patch doesn't fix the colibri_t20 board, even though it has the same
issue, since Marcel already sent a patch for that.

ARM: tegra: fix USB ULPI PHY reset signal inversion confusion

USB ULPI PHY reset signals are typically active low. Consequently, they
should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in
the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use.
However, in DT properties that U-Boot does use, the value has been set to
0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot.

This change fixes the DT to correctly represent the HW, and fixes the
Tegra USB driver to cope with the fact that dm_gpio_set_value() internally
handles any inversions implied by the DT value GPIO_ACTIVE_LOW.

mmc: tegra: use correct alias for SDHCI/MMC nodes

The Tegra MMC driver currently honors "sdhci" entries in /aliases. The
MMC core however uses "mmc" entries in /aliases. This difference will be
relevant once the Tegra MMC driver is converted to DM, and the MMC core
handles alias lookups. To avoid issues during that conversion, fix the
Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC
core does.

dts: move device tree sources to arch/$(ARCH)/dts/

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.
