The #ifdef guards around these are wrong, resulting in warnings
in certain configurations:
drivers/usb/dwc3/dwc3-qcom.c:244:12: error: 'dwc3_qcom_resume' defined but not used [-Werror=unused-function]
static int dwc3_qcom_resume(struct dwc3_qcom *qcom)
^~~~~~~~~~~~~~~~
drivers/usb/dwc3/dwc3-qcom.c:223:12: error: 'dwc3_qcom_suspend' defined but not used [-Werror=unused-function]
static int dwc3_qcom_suspend(struct dwc3_qcom *qcom)
This replaces the guards with __maybe_unused annotations to shut up
the warnings and give better compile time coverage.

Fix to return error code -ENODEV from the get device failed error
handling case instead of 0, as done elsewhere in this function.

It appears that a "#define DEBUG" was left in on the recent patch
landed for the Qualcomm DWC3 glue driver. Let's remove it.

DWC3 controller on Qualcomm SOCs has a Qscratch wrapper.
Some of its uses are described below resulting in need to
have a separate glue driver instead of using dwc3-of-simple:
- It exposes register interface to override vbus-override
and lane0-pwr-present signals going to hardware. These
must be updated in peripheral mode for DWC3 if vbus lines
are not connected to hardware block. Otherwise RX termination
in SS mode or DP pull-up is not applied by device controller.
- pwr_events_irq_stat support to check if USB2 PHY is in L2 state
before glue driver proceeds with suspend.
- Support for wakeup interrupts lines that are asserted whenever
there is any wakeup event on USB3 or USB2 bus.
- Support to replace pip3 clock going to DWC3 with utmi clock
for hardware configuration where SSPHY is not used with DWC3.

Now that we have a generic dwc3-of-simple.c, we can
use that instead of maintaining dwc3-qcom.c which is
extremely similar.

those two messages are informing that the clock
doesn't exist; that, however, is a valid situation
and driver continues just fine by ignoring the error.

There is no need to init .owner field.
Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"
This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

DWC3 glue layer is hardware layer around Synopsys DesignWare
USB3 core. Its purpose is to supply Synopsys IP with required
clocks, voltages and interface it with the rest of the SoC.
