The UDC/OTG controller could be switched to a host mode and the TXFILLTUNING register needs to be programmed properly for the host mode. Hence specify the TX FIFO threshold in the UDC SoC info.

Tegra PHY driver now supports waking up controller from a low power mode. Enable runtime PM in order to put controller into the LPM during idle.

Add USB host mode to the Tegra HDRC driver. This allows us to benefit from support provided by the generic ChipIdea driver instead of duplicating the effort in a separate ehci-tegra driver.

Rename all occurrences in the code from "udc" to "usb" and change the Kconfig entry in order to show that this driver supports USB modes other than device-only mode. The follow up patch will add host-mode support and it will be cleaner to perform the renaming separately, i.e. in this patch.

The OF core adds an alias based on the OF device ID table, which is enough to have the driver autoloaded. The legacy MODULE_ALIAS macro was relevant to a pre-OF board files which manually created platform devices, this is irrelevant to the modern ARM kernels since devices are created by the OF core. Remove the unnecessary macro in order to keep the driver's code cleaner.

if of_find_device_by_node() succeed, usbmisc_get_init_data() doesn't have
a corresponding put_device(). Thus add put_device() to fix the exception
handling for this function implementation.
