usb: gadget: at91-udc: fix irq and iomem resource retrieval

Browse Source 
commit 886c7c426d upstream.

When using dt resources retrieval (interrupts and reg properties) there is
no predefined order for these resources in the platform dev resource
table. Also don't expect the number of resource to be always 2.
