usb: musb: add names for IRQs in structure resource
Soon resource data will get automatically populated from a set of autogenerated data from TI's hardware database for the OMAP platform. Such database, might not have resources at the expected order by the current drivers. While we could hack in some exceptions to that tool to generate resources in a specific order, it seems less fragile to use the resource name instead. That way, no matter what order the resources are generated, the driver still work. Modified the OMAP, Blackfin and Davinci architecture files to add the name of the IRQs in the resource structures and musb driver to use the platform_get_irq_byname() api to get the device and dma irq numbers instead of using the index.
