USB OTG devices are not required to support external hubs. This adds a
configuration option to disable that support.

This patch associates hub suspend and resume logic (including for root hubs)
with CONFIG_PM -- instead of CONFIG_USB_SUSPEND as before -- thereby unifying
two troublesome versions of suspend logic into just one. It'll be easier to
keep things right from now on.
- Now usbcore _always_ calls hcd->hub_suspend as needed, instead of
only when USB_SUSPEND is enabled:
* Those root hub methods are now called from hub suspend/resume;
no more skipping between layers during device suspend/resume;
* It now handles cases allowed by sysfs or autosuspended root hubs,
by forcing the hub interface to resume too.
- All devices, including virtual root hubs, now get the same treatment
on their resume paths ... including re-activating all their interfaces.
Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and
updates the Kconfig to match the new definition of USB_SUSPEND: it provides
(a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream
from any device configuration which supports it.
This calls for minor followup patches for most HCDs (and their PCI glue).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
