Avoiding phy powerdown in host mode so that it can be wake up by devices. Set GENPD_FLAG_ACTIVE_WAKEUP flag to keep usb30_prim gdsc active when wakeup capable devices are connected to the host. Using PDC interrupts instead of GIC interrupst to support wakeup in xo shutdown case. Changes in v3: Removed need_phy_for_wakeup flag and by default avoiding phy powerdown. Addressed Matthias comments and added entry for DEV_SUPERSPEED. Added suspend_quirk in dwc3 host and moved the dwc3_set_phy_speed_flags. Added wakeup-source dt entry and reading in dwc-qcom.c glue driver. Changes in v2: Dropped the patch in clock to set GENPD_FLAG_ACTIVE_WAKEUP flag and setting in usb dwc3 driver. Separated the core patch and glue driver patch. Made need_phy_for_wakeup flag part of dwc structure and hs_phy_flags as unsgined int. Adrressed the comment on device_init_wakeup call. Corrected offset for reading portsc register. Added pacth to support wakeup in xo shutdown case.
