Subject[PATCH] usb: dwc2: Fix phy_reset_work compile error for peripheral-only config
Date
In commit a0a493835f9a ("usb: dwc2: optionally assert phy reset when
waking up") I added to code that is compiled in both the host and
peripheral configs but it referenced a structure member that I added
to a section that was only there for host or dual-mode configs. That
led to the compile error:

>> drivers/usb/dwc2/core_intr.c:448:25: error: 'struct dwc2_hsotg' has no member named 'phy_reset_work'

We'll add a little helper function to schedule the work and then we
can have a dummy version of that helper in peripheral-only mode.

Fixes: a0a493835f9a ("usb: dwc2: optionally assert phy reset when waking up")
