ARM: dts: msm: Update USB interrupt trigger types on Lahaina

Change "dp_hs_phy_irq" and "dm_hs_phy_irq" IRQ trigger types
to rising-edge instead of dual-edge in order to match with
what the driver is requesting. This avoids a error produced
when the driver is removed and reprobed as the kernel IRQ
subsystem will have updated the trigger type to the driver's
request type, and on the subsequent probe results in the
following errors when IRQ mapping is performed due to the
flags mismatch:

  [  885.423166] irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000!
  [  885.439468] irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000!
