drivers/usb/host/ehci-fsl: Fix interrupt setup in host mode.

In patch a1a2b7125e10 (Drop static setup of IRQ resource from DT
core) we stopped platform_get_resource() from returning the IRQ, as all
drivers were supposed to have switched to platform_get_irq()
Unfortunately the Freescale EHCI driver in host mode got missed. Fix
it.

Fixes: a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core")
