This adds type-checking to pm_message_t, so that people can't confuse it
with int or u32. It also allows us to fix "disk yoyo" during suspend (disk
spinning down/up/down).
[We've tried that before; since that cpufreq problems were fixed and I've
tried make allyes config and fixed resulting damage.]

This patch has a one line oops fix, plus related cleanups.
- The bugfix uses microframe scheduling data given to the hardware to
test "is this a periodic QH", rather than testing for nonzero period.
(Prevents an oops by providing the correct answer.)
- The cleanup going along with the patch should make it clearer what's
going on whenever those bitfields are accessed.
The bug came about when, around January, two new kinds of EHCI interrupt
scheduling operation were added, involving both the high speed (24 KBytes
per millisec) and low/full speed (1-64 bytes per millisec) microframe
scheduling. A driver for the Edirol UA-1000 Audio Capture Unit ran into
the oops; it used one of the newly supported high speed modes.

Various minor EHCI updates
* Dump some more info in the debug dumps, notably the product
description (e.g. chip vendor), BIOS handhake flags, and
debug port status (when it's not managed by the HCD).
* Minor updates to the BIOS handoff code: always flag the HCD
as owned by Linux (in case BIOS doesn't grab it "early"),
and on the buggy-BIOS path always match the "early handoff"
code and forcibly disable SMI IRQs.
* For the disabled 64bit DMA support, there's now a constant
to use for the mask; use it.

This moves a kref into the main hcd structure, which detaches it from
the class device structure.

This patch includes minor "sparse -Wbitwise" updates for the PCI based
HCDs. Almost all of them involve just changing the second parameter of the
suspend() method to a pm_message_t ... the others relate to how the EHCI
code walks in-memory data structures. (There's a minor bug fixed there too
... affecting the big-endian sysfs async schedule dump.)

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!
