USB: dwc3: qcom: fix wakeup after probe deferral

commit 85e56a922b0795c5f47f978ae6bce0ef4489c1da
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8N1WC

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=85e56a922b0795c5f47f978ae6bce0ef4489c1da



--------------------------------

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.
