Add basic i2c driver for Tegra2 with 8- and 16-bit address support.
The driver requires CONFIG_OF_CONTROL to obtain its configuration
from the device tree.

This adds basic support for the Tegra2 USB controller. Board files should
call board_usb_init() to set things up.

Configuration is performed through the FDT, with aliases used to set the
order of the ports, like this fragment:

        aliases {
		/* This defines the order of our USB ports */
                usb0 = "/usb@0xc5008000";
                usb1 = "/usb@0xc5000000";
        };

Ensure that transmit and receive buffers are cache-line aligned.
Invalidate cache for each packet as received, update receive buffer
descriptors one cache line at a time, flush cache before transmitting.

This implements generic bounce buffer at the end of MMC command submission
chain. Therefore if unaligned data are passed, they are copied. This stuff
should be pushed down into the MMC subsystem to squash all places generating
these unaligned data.

twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively
enabling the supply), and only then sets vsel (selects voltage). This could
lead to wrong voltage for a short time, or even long time if second i2c
write fails.

Fix this by writing vsel first and device group after that. Also
introduce error checking to not enable the supply if we failed to set
the voltage, and start logging errors as power supply problems are
usually important.

This patch fixes a few bugs in USB device controller driver.
The fixes are as follows

2. Endpoint other than endpoint 0 (control endpoint) are initialized
only if usb state machine reaches STATE_ADDRESSED or above
3. Zero length packet handling corrected
4. Dead code removed
5. Bulk out endpoint returns after servicing 1 interrupt and returns
back to service if more interrupts are pending

A few subsystems are using the same define "NAMESIZE".  This has been
working so far because they define it to the same number.  However, I
want to change the size of eth_device's NAMESIZE, so rather than tweak
the define names, simply drop references to it.  Almost no one does,
and the handful that do can easily be changed to a sizeof().
