in struct driver_d which gets overwritten with usb_driver->name

ehci: speed up initialization
According to EHCI specification v1.0, the controller should stabilize
the power on a port at most 20 ms after the port power bit transition.
So, we put this setting in the virtual descriptor corresponding field,
(bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each
controller initialization/enumeration.

for chache handling the ehci driver iterates over the hardware lists
of QHs/TDs. As we have a fixed number of maximum entries in this lists
we can allocate them as arrays and and clean/invalidate the arrays
instead which is much simpler. While at it, move the allocation to
ehci_probe so that we do not lose memory each time ehci_init is called.
Also, use memalign to allocate the QHs/TDs.

The timings of the poller calling have changed, digging out
a latent bug in pxa27x udc controller.
The polling routine is called before the probe function is
called, and the driver internal are not initialized at that
time. This triggers a NULL pointer exception.
Fix it by moving poller registration after driver probe.

USB: Remove __attribute__ ((packed)) for struct ehci_hccr and ehci_hcor
Remove __attribute__ ((packed)) to prevent byte access to soc
registers in some gcc versions.
Having patches to enable ehci for the BeagleBoard lying around for
several months, this one was the show-stopper.
Switched to align(4), rather than remove the attribute, per suggestion
from Alexander.
Credits have to go to Laine Walker-Avina <lwalkera@ieee.org> for
finding the problem.

- bwPollTimeout is set to 10 ms, from the DFU spec, this
is the minimum time, in milliseconds, that the host should
wait before sending a subsequent DFU_GETSTATUS request.
Without this, I get 25 seconds value and dfu-util waits twice 25s
during download
- when in IDLE and receiving DETACH, first return 0 to make
dfu-util happy, then use a dfudetach variable to exit dfu
(without an USB reset as per the comment on line 425) and
return to runtime mode.

In u-boot this function was transmitting a cmdlen of 12, by the initial

u-boot, which probably also need a fix.

As USB can have its cable plugged out anytime, make the
serial gadget reliable in case of unplugging :
- unregister the gadget_serial provided console
- don't stay forever in the read loop if connection was cut
This behaviour relies on correct implementation of
usb_gadget_poll(), which should return an error if the USB
cable was removed.
