[PATCH 5/6] usb: host: ehci-tegra: Use devm_ioremap_resource instead of devm_ioremap

[Vivek Gautam]

Using devm_ioremap_resource() API should actually be preferred over
devm_ioremap(), since the former request the mem region first and then
gives back the ioremap'ed memory pointer.
devm_ioremap_resource() calls request_mem_region(), therby preventing
other drivers to make any overlapping call to the same region.
