Subject: USB: dwc3: qcom: fix wakeup after probe deferral

From: Johan Hovold <johan+linaro@xxxxxxxxxx>

commit 41f5a0973259db9e4e3c9963d36505f80107d1a0 upstream.

The Qualcomm glue driver is overriding the interrupt trigger types
defined by firmware when requesting the wakeup interrupts during probe.

This can lead to a failure to map the DP/DM wakeup interrupts after a
probe deferral as the firmware defined trigger types do not match the
type used for the initial mapping:

	irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000!
	irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000!

Fix this by not overriding the firmware provided trigger types when
requesting the wakeup interrupts.
