The Tegra XHCI driver currently assumes the XUSB power partitions have been enabled by the bootloader. This is not for the Tegra210 Smaug board and so cause the kernel to hang when enabling XHCI support. Although the XHCI driver itself needs to manage these partitions, for now enable the partitions if the XHCI driver is enabled. In order to do this I have made a fundamental change to the PMC driver to initialise the power partitions during early init. A benefit of this is that if CONFIG_PM_GENERIC_DOMAINS is not enabled, then we can simply turn on the partitions early before any devices are probed. This is based upon the PMC fixes series [0].
