Tegra30 and Tegra114 are compatible except PLL parameters.
Tested on Tegra30 Cardhu, and Tegra114 Dalmore
platforms. All works well.

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.

Remove unneeded headers, function prototype and stale comment, that
doesn't match the actual codebase anymore.

This adds the required code to set up a ULPI USB port. It is
mostly a port of the Linux ULPI setup code with some tweaks
added for more correctness, discovered along the way of
debugging this.
To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT
have to be set in the board configuration file.

EHCI interface now supports more than one controller. Wire up our usb functions
to use this new interface.

This is make naming consistent with the kernel and devicetree and in
preparation of pulling out the common tegra20 code.
