You also need minItems 14 here.

And here, I think.

The naming here is inconsistent and interrupts should not have "_irq"
suffixes (even if some of the current ones do for historical reasons).

I believe these should be named

	pwr_event_1
	dp_hs_phy_1
	dm_hs_phy_1
	ss_phy_1

	pwr_event_2
	dp_hs_phy_2
	dm_hs_phy_2
	ss_phy_2

	pwr_event_3
	dp_hs_phy_3
	dm_hs_phy_3

	pwr_event_4
	dp_hs_phy_4
	dm_hs_phy_4

or similar and be grouped by port while using the the
qcom,sc8280xp-dwc ordering for the individual lines.

Side note: Please note how the above interrupt properties can also be
used to infer the number of HS and SS ports.
