ARM: ns9750dev: remove remainders of dead board

Commit 8b710b1 started removing code for the unmaintained "ns9750dev"
board; the board support is still broken, and not included anywhere in
the Makefile or boards.cfg.  Remove the remaining dead code.

tegra: usb: make controller init functions more self contained

There is no need to pass around all those parameters. The init functions
are able to easily extract all the needed setup info on their own.

This allows to move out the controller init into ehci_hcd_init later
on, without having to save away global state for later use  and thus
bloating the file global state.

tegra: usb: move controller init into start_port

tegra: usb: move implementation into right directory

This moves the Tegra USB implementation into the drivers/usb/host
directory. Note that this merges the old
/arch/arm/cpu/armv7/tegra20/usb.c file into ehci-tegra.c. No code
changes, just moving stuff around.

v2: While at it also move some defines and the usb.h header file to make
usb driver usable for Tegra30.
NOTE: A lot more work is required to properly init the PHYs and PLL_U on
Tegra30, this is just to make porting easier and it does no harm here.

tegra: usb: move [start|stop]_port into ehci_hcd_[init|stop]

The ehci_hcd entry points were just calling into the Tegra USB
functions. Now that they are in the same file we can just move over the
implementation.

Tegra: I2C: Add T114 clock support to tegra_i2c driver

T114 has a slightly different I2C clock, with a new (extra) divisor
in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C
clock is 100KHz +/- 3Hz on my Saleae Logic analyzer.

Added a new entry in compat_names for T114 I2C since it differs
from the previous Tegra SoCs. A flag is set when T114 I2C HW is
found so new features like the extra clock divisor can be used.

Tegra114: fdt: Update DT files with I2C info for T114/Dalmore

T114, like T30, does not have a separate/different DVC (power I2C)
controller like T20 - all 5 I2C controllers are identical, but
I2C5 is used to designate the controller intended for power
control (PWR_I2C in the schematics). PWR_I2C is set to 400KHz.

Tegra: fdt: Change /include/ to #include for C preprocessor

dts Makefile has the arch & board include paths added to DTS_CPPFLAGS.
This allows the use of '#include "xyz"' in the dts/dtsi file which

ARM: tegra: implement WAR for Tegra114 CPU reset vector

A Tegra114 HW bug prevents the main CPU vector from being modified under
certain circumstances. Tegra114 A01P and later with a patched boot ROM
set the CPU reset vector to 0x4003fffc (end of IRAM). This allows placing
an arbitrary jump instruction at that location, in order to redirect to
the desired reset vector location. Modify Tegra114's start_cpu() to make
use of this feature. This allows CPUs with the patched boot ROM to boot.
