clock: msm: Add gcc_usb30_master_clk to USB HS/SS PHY devices

The USB PHY device is normally separate from the SS USB controller
driver, but on 8974 and 8084, the PHYs actually share IO register
space with the controller itself. There may be situations in which
the PHY driver needs to access those shared registers after the
controller has already turned off those clocks for low power mode,
and would result in unclocked access. Add additional clock entries
for the USB3 master clock to the HS and SS PHY devices in order to
allow their drivers to enable it directly as needed. This will
allow the PHY drivers to not have to rely on the controller to turn
it on first.
