usb: dwc3: fix dwc3_readl() and dwc3_writel() calls in dwc3_ulpi_setup()

The dwc3_ulpi_setup() calls the register read and write calls with
dwc3->regs when both these calls take the dwc3 structure directly.

Chnage these two calls to fix the following sparse warning, and
possibly a nasty bug in the dwc3_ulpi_setup() code:

drivers/usb/dwc3/core.c:796:45: warning: incorrect type in argument 1 (different address spaces)
drivers/usb/dwc3/core.c:796:45:    expected struct dwc3 *dwc
drivers/usb/dwc3/core.c:796:45:    got void [noderef] __iomem *regs
drivers/usb/dwc3/core.c:798:40: warning: incorrect type in argument 1 (different address spaces)
drivers/usb/dwc3/core.c:798:40:    expected struct dwc3 *dwc
drivers/usb/dwc3/core.c:798:40:    got void [noderef] __iomem *regs
