UPSTREAM: usb: dwc2: Rename CONFIG_DWC2_UTMI_PHY_WIDTH to CONFIG_DWC2_UTMI_WIDTH

For some reason from day one we used to have both CONFIG_DWC2_UTMI_WIDTH
mentioned in dwc2.h and in scripts/config_whitelist.txt but never really used
and CONFIG_DWC2_UTMI_PHY_WIDTH used in real code in dwc2.c (but never
defined).

Moreover even though CONFIG_DWC2_UTMI_WIDTH might be either 8 or 16
depending on hardware (and the same is said in a comment for it in
dwc2.h) but then 8 is hardcoded in the header leaving no ability to
override this value in board's configuration.

usb: dwc2: disable erroneous overcurrent condition

For the case where an external VBUS is used, we should enable the external
VBUS comparator in the driver. This would prevent an unnecessary overcurrent
error which would then disable the host port.

The overcurrent condition was happening on the SoCFPGA Cyclone5 devkit, thus
USB was not working on the devkit. This patch fixes that problem.

usb: dwc2: Add SPLIT INTERRUPT transaction support

CSPLITs for INTERRUPT transactions have to be scheduled in each microframe
following the SSPLIT. INTERRUPT transfers are executed in the next even/
odd microframe depending on the HCCHAR_ODDFRM flag.

As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have
failed (transport error) without the error being detected by the host
driver. If the last CSPLIT is not received within 4 microframes after the
SSPLIT there was a transaction error and the complete transaction has
to be restarted.

usb: dwc2: detect device speed correctly

This doesn't make my LS keyboard work any better, but it does at least
report the correct speed in "usb tree".

usb: dwc2: Add driver for Synopsis DWC2 USB IP block

This is the USB host controller used on the Altera SoCFPGA and Raspbery Pi.

This code has three checkpatch warnings, but to make sure it stays at least
readable and clear, these are not fixed. These bugs are in the USB request
handling combinatorial logic, so any abstracting of those is out of question.

Tested on DENX MCV (Altera SoCFPGA 5CSFXC6C6U23C8N) and RPi B+ (BCM2835).
