ARM: dts: msm: Change trigger type of dp_hs_phy_irq,dm_hs_phy_irq for kona

Irq type mentioned in dwc3-msm at usb_irq_info for dp_hs_phy_irq and
dm_hs_phy_irq is trigger rising but irq type for the same in kona dtsi is
edge both because of which mismatch is seen when mapping dp_hs_phy_irq
and dm_hs_phy_irq. This mismatch results in failure to register interrupts
with PDC controller.

To fix the type mismatch issue change the trigger type of dp_hs_phy_irq and
dm_hs_phy_irq to EDGE RISING.
