tegra_fuse_readl() can be called from drivers at any time. If this API is
called before tegra_fuse_probe(), we end up enabling clock before it is
registered. Add check for fuse clock in tegra_fuse_readl() and return
corresponding error if any.

wrong remap of user memory.
Check if address returned by usb_alloc_coherent failed in vmalloc range
and if yes, use remap_vmalloc_range API, else use remap_pfn_range to remap

On Tegra210, usb2 only otg/peripheral ports dont work in device mode.
They need an assosciated usb3 port to work in device mode. Identify
an unused usb3 port and assign it as a fake USB3 port to USB2 only
