dt-bindings: phy: qcom-edp: Add missing clock for X Elite

Browse source

commit 6b99eeacf6 upstream.

On X Elite platform, the eDP PHY uses one more clock called ref.

The current X Elite devices supported upstream work fine without this
clock, because the boot firmware leaves this clock enabled. But we should
not rely on that. Also, even though this change breaks the ABI, it is
needed in order to make the driver disables this clock along with the
other ones, for a proper bring-down of the entire PHY.

So attach the this ref clock to the PHY.
