usb: dwc3: core: Power-off core/PHYs on system_suspend in host mode
Commit 689bf72c6e0d ("usb: dwc3: Don't reinitialize core during
host bus-suspend/resume") updated suspend/resume routines to not
power_off and reinit PHYs/core for host mode.
It broke platforms that rely on DWC3 core to power_off PHYs to
enter low power state on system suspend.
Perform dwc3_core_exit/init only during host mode system_suspend/
resume to addresses power regression from above mentioned patch
and also allow USB session to stay connected across
runtime_suspend/resume in host mode. While at it also replace
existing checks for HOST only dr_mode with current_dr_role to
have similar core driver behavior for both Host-only and DRD+Host
configurations.
