Added udc-core.c from linux kernel 3.19-rc1 (97bf6af1f9) to u-boot.
This will be adapted to work with u-boot in the
following patches.
Adding support for udc will help to seamlessly port dwc3 driver from
linux kernel to u-boot (since dwc3 uses udc-core) and it'll also help
to add support for multiple gadget controllers to be functional at the
same time.
All other gadget drivers can also be adapted to use udc-core.

IIUC, interrupt transfers are NAK'd by devices until they wish to trigger
an interrupt, and e.g. EHCI controllers retry these in HW until they are
ACK'd. However, DWC2 doesn't seem to retry, so we need to do this in SW.
In practice, I've seen DWC2_HCINT_FRMOVRUN happen too. I'm not quite sure
what this error implies; perhaps it's related to how near the end of a
USB frame we're at when the interrupt transfer is initiated? Anyway,
retrying this temporary error seems to be necessary too.
With all these commits applied, both my USB keyboards (one LS Lenovo and
one FS Dell) work correctly when there is no USB hub between the SoC and
the keyboard; We still need split transactions to be implemented for hubs
to work.

As best I can tell, there's no difference between bulk and interrupt
transfers in terms of how the HW should be programmed, at least given
that we're executing one transaction at a time rather than scheduling
them into frames for maximum throughput.
This patch ends up sharing the toggle bit state between bulk and
interrupt transfers on a particular EP. However I believe this is fine;
AFAIK a given EP either uses bulk or interrupt transfers and doesn't mix
them.
This patch doesn't do anything with the "interval" parameter for
interrupt transfers, but then most other USB controller drivers in U-Boot
don't either.
It turns out that one of my keyboards is happy to work using control
transfers but the other only gives non-zero "HID reports" via interrupt
transfers.

When I created wait_for_chhltd(), I noticed that some instances of the
code it replaced expected the ACK bit to be set and others didn't. I
assumed this was an accidental inconsistency in the code, so wrote
wait_for_chhltd() to always expect ACK to be set. This code appeared to
work correctly for both enumeration of USB keyboards and operation of
USB Ethernet devices. However, this change broke USB Mass Storage (at
least my USB SD card reader). This change reverts to exactly the
original behaviour. I'm not sure why the ACK bit isn't always set
(perhaps a quirk in the USB HW or DWC2 controller), but the code works
this way!

Each USB transfer is split up into chunks that are held in an aligned
buffer. This imposes a limit on the size of each chunk, but no limit on
the total size of transferred data. Fix the logic in chunk_msg() not to
reject large transfers, but simply take the size of the aligned buffer
into account when calculating the chunk size.

The original aligned_buffer usage:
a) Uselessly copied data into the aligned buffer even for IN
transactions. Fix this my making the copy conditional.
b) Always programmed the HW to transfer to/from the start of the aligned
buffer. This worked fine for OUT transactions since the memcpy copied
the OUT data to this location too. However, for large IN transactions,
since the copy from the aligned buffer to the "client" buffer was
deferred until after all chunks were transferred. it resulted in each
chunk's transfer over-writing the data for the first transfer. Fix
this by copying IN data as soon as it's received.

The usb0 / otg phy on sunxi boards has a bug where it wrongly detects a
high speed squelch on usb reset deassert when a lo speed device is plugged in.
The android kernel has a work around for this in the form of temporary
disabling the phy's squelch detection on reset deassert, this commit adds
the same workaround to the u-boot sunxi musb code, thereby fixing various usb
lo speed devices not working.
Tested with a (before non working) usb keyboard and a usb 2.4 GHz wireless
keyboard/mouse combo receiver.

This enables the musb glue layer to use the AXP221's VBUS detection
function to check for VBUS. This fixes otg support on the A23 q8h
tablets.
Note that u-boot never calls musb_shutdown(), so once VBUS is enabled,
it is never disabled until the system is powered off, or the OS does
so. This can be used to our advantage to keep VBUS powered into the
OS, where support for AXP221 is not available yet.

When booting from USB peripheral boot, the bootrom will not properly deinit the
MUSB controller, which doesn't clearly indicate an USB disconnection to the host
and leaves U-Boot to deal with the state of the previous USB session.
On some host controller drivers (e.g. xhci_hcd), this ends up in a failure
during set address, caused by the lack of proper disconnection notification.
Resetting the controller early in U-Boot notifies the host of the disconnection
and doesn't hurt other use cases.
