Tegra's EHCI controllers only have a single PORTSC register. Configure
U-Boot to know this. This prevents e.g. ehci_shutdown() from touching
non-existent registers.

<asm/arch-tegra/tegra.h> needs to use CONFIG_TEGRA* to conditionalize
some definitions, since some modules moved between generations. Move
the definition of CONFIG_TEGRAnn to a header that's included earlier,
so that it's set by the time tegra.h needs to use it.

Fix the timeout issue after running "bootp" command in u-boot
console. For example you see "EHCI timed out on TD- token=0x...".
TXFIFOTHRES bits of TXFILLTUNING register should be set to 0x10
after a controller reset and before RUN bit is set
(per technical reference manual).

Currently all Tegra SoCs are assumed to have 32 byte cache lines. This
isn't true for Tegra114, however, which uses 4 Cortex-A15 cores and
therefore uses a cache line size of 64 bytes. Move the cache line size
setting to the per-SoC common configuration file.

Add USB EHCI, storage and network support.

Tested on Tegra30 Cardhu, and Tegra114 Dalmore
platforms. All works well.

All Tegra devices will need CONFIG_BOUNCE_BUFFER. Move it to
tegra-common.h to ensure it's always set.

Tested on my Cardhu-A04 tablet, eMMC and SD-Card work fine, can load
a kernel off of an SD card OK, card detect works, and the env is now
stored in eMMC (end of the 2nd 'boot' sector, same as Tegra20).

Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such,
some CPU errata exist, and must be worked around.

These must be worked around in the bootloader, since in general, the
kernel (especially a multi-platform kernel) needs to support being
launched in non-secure mode (normal world), and hence may not be able
to write to the CP15 register to enable these workarounds.

Tested all 5 'buses', i2c probe enumerates device addresses on all
but dev 4 (I2C4) [no devices on that bus on my Cardhu].

Note that this uses the extant tegra_i2c.c driver w/o modification.

This build is stripped down. It boots to the command prompt.
GPIO is the only peripheral supported. Others TBD.

include/configs/tegra-common.h now holds common config options
for Tegra SoCs.
