[PATCH 1/2] usb: dwc3: core: Fix warnings when building without driver model

[Alban Bedel]

Commit f150b8d28b4e ("usb: dwc3: Enable undefined length INCR burst
type") introduced code that assign the content of dwc->dev to a
variable. But in u-boot the type of this field changes if building
with driver model enabled or not. As this variable is then only used
once just remove it and use the struct field directly.

Another issued was also introduced in commit fb146fbc1ae5 ("usb: dwc3:
core: stop the core when it's removed") which define a static function
which is only used when the driver model is enabled. Add ifdef around
this function to suppress the warning when building without driver
model.
