In the suspend / resume callbacks, qmp->phy could be NULL because PHY is
created after the PM ops are enabled, which lead to the NULL pointer
deference.
Internally issue is reported on qcom-qmp-usb driver. Since the fix is
applicable to legacy and usbc drivers, incoporated the fixes for those
driver as well.
qcom-qmp-usb-legacy and qcom-qmp-usbc drivers are splitted out from
qcom-qmp-usb driver in v6.6 and v6.9 respectively. So splitted the
changes into 3, for ease of backporting.
