usb: host: xhci-tegra: Avoid a fixed duration sleep
Do not use a fixed duration sleep to wait for the DMA controller to
become ready. Instead, poll the L2IMEMOP_RESULT register for the VLD
flag to determine when the XUSB controller's DMA master is ready.
Based on work by JC Kuo <[email protected]>.
