[RFC 4/5] usb: dwc3-exynos: enable async suspend/resume

[Yuvaraj Kumar C D <yuvaraj.cd@gmail.com>]

From: Andrew Bresticker <abrestic@chromium.org>

In addition to enabling async suspend/resume on the xhci-plat device,
we must enable it for the dwc3-exynos platform device in order to make
the full USB stack resume asynchronously.  Like the xhci-plat, ehci-s5p,
and ohci-exynos drivers, there are no outside dependencies which would
make resuming the dwc3-exynos driver asynchronously unsafe.
