This patch makes some cosmetic changes to dummy_hcd:
Minor alterations of comments and whitespace.
Replace USB_PORT_FEAT_xxx with USB_PORT_STAT_xxx. This is
appropriate as the values are stored in a status variable
and they aren't feature indices. Also it allows the
elimination of a bunch of awkward bit shift operations.

Partial OTG support for dummy_hcd, mostly as a framework for further work.
It emulates the new OTG flags in the host and peripheral frameworks, if
that option is configured. But it's incomplete:
- Resetting the peripheral needs to clear the OTG state bits;
a second enumeration won't work correctly.
- This stops modeling HNP right when roles should switch the first time.
It should probably disconnect, then set the usb_bus.is_b_host and
usb_gadget.is_a_peripheral flags; then it'd enumerate almost normally,
except for the role reversal. Roles could then switch a second time,
back to "normal" (with those flags cleared).
- SRP should be modeled as "resume from port-unpowered", which is
a state that usbcore doesn't yet use.
HNP can be triggered by enabling the OTG whitelist and configuring a
gadget driver that's not in that list; or by configuring Gadget Zero
to identify itself as the HNP test device.

This patch changes the host controller drivers; they no longer need to
register their root hubs because usbcore will take care of it for them.

This patch changes the HCDs that used the old hub_set_power_budget call,
making them use the new hcd->power_budget field instead.

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!
