This driver is meant to be used with any OHCI-compatible host
controller in case if there's no need for platform-specific
glue such as setup of controller or PHY's power mode via
GPIOs etc.

With the old order of initialization the hcor pointer has been setup to
the same address as Exynos EHCI base address (0x12110000 instead of
0x12110010).
Such behaviour was caused by reading value of 0 instead of 0x10 from EHCI
HCCPBASE register without doing proper clock initialization before.

To fix this problem hcor initialization has been moved after USB PHY setup.
Now ehci_readl(&ctx->hcd->cr_capbase) returns correct value.

The driver is actually for the Designware DWC2 controller.
This patch renames the global s3c_udc.h header to dwc2_udc.h.

The rename is done automatically:
	$ sed -i "s/s3c_udc\.h/dwc2_udc.h/g" \
		`git grep "s3c_udc\.h" | cut -d : -f 1`

The driver is actually for the Designware DWC2 controller.
This patch is the second and final to rename global symbol,
the s3c_udc_probe() function.

The rename is done automatically:
	$ sed -i "s/s3c_udc_probe/dwc2_udc_probe/g" \
		`git grep s3c_udc_probe | cut -d : -f 1`

This patch is the first to rename global symbol, the struct
s3c_plat_otg_data.

The rename is done automatically:

The s3c-otg IP block is in fact a DWC2 OTG one, so finally rename the
config option to make it less misleading. No functional change, just
a mechanical change done using the following script:

  git grep USB_GADGET_S3C_UDC_OTG | cut -d : -f 1 | sort -u | \
  while read line ; do
    sed -i "s/USB_GADGET_S3C_UDC_OTG/USB_GADGET_DWC2_OTG/g" $line ;
  done

Tweak the comments in the driver to reflect this fact.
