This ought to fix the NS9750 init issue, and make the AMD756 case
at least somewhat better.  It makes the init go "by the book" in more
ways, and formalizes one quirk.

Various OHCI init/reset cleanups for different silicion environments:

 - Reset a bit more "by the book".

    * Define a new quirk flag for the SiS and OPTi problem seen earlier.
      Since 2.4 we've always worked around that quirk, even though we've
      not seen that on other chips; but it's "wrong" and doesn't work on
      some chips (notably NetSilicon NS9750).

      The quirk still seems to be needed for SiS, but either this test
      machine is too fast for the OPTi problem to show up, or the frame
      timing setup problem there came from a now-fixed bug.

    * Look at the HC state before resetting it; depending on whether
      it was previously owned by BIOS, SMM, an OS, or nobody, different
      USB signaling (and timings) might be needed.

    * Re-init the frame timings right after soft reset, rather than
      later (potentially too much later).

    * Restore a reset in the PCI startup code, so this logic more closely
      resembles the non-PCI paths (future code sharing).  It also makes it
      easier to guarantee a 1-millisecond ceiling between reset and "go".

      An earlier reset is being done to help workaround BIOS-related
      problems on some boards, but we may need an even earlier one
      (as a PCI quirk, before IRQs get reconfigured).

 - Add an explicit #define to disable the BIOS/SMM handoff; it's
   not just HPPA, many embedded chips don't expect BIOS either.

 - There are reports of AMD 756 machines disliking the OHCI suspend
   patch of a few months back.  Erratum #10 partly explains that, so
   now root hubs won't autosuspend on those Slot-A era chips.

 - Other minor fixes

    * We've got lots of non-PCI OHCI now too, so comments shouldn't
      be assuming all-is-pci!

    * Hey, it's unsafe to call hc_reset() in IRQ (after unrecoverable
      error); so just force a soft reset, don't do the whole thing.

Tested on half a dozen different OHCI versions, but maybe some other
versions of OHCI will be sensitive to one of these changes.

This patch adds support for suspending, resuming, and remote wakeup
detection on root hub ports to the UHCI driver.  It doesn't add support
for suspending or resuming the root hub itself (beyond what's already
there) -- that will require considerably more work.  But at least devices
plugged directly into the computer will interact nicely with power
management.

Of lesser importance, the patch also simplifies some constant expressions.

This patch changes the only places in usbcore where usb_unlink_urb() is
still used for synchronous unlinking; now they will use usb_kill_urb().
As it turns out, there were only a couple of changes needed.

This still leaves all the drivers to audit!

Both work, but the latter can cause warnings in user space
from compilers that don't like using undefined identifiers
in preprocessor expressions (quite reasonable).

The checkbin target on PPC32 isn't quite right.

First, one of the tests (to ensure that some instructions are known to
gas) is never actually invoked because 'checkbin' doesn't know about
stuff set in .config, so we always have the 'else' case run.  This
changes to always running the test and telling the user to upgrade to at
least binutils 2.12.1.

The next problem is that we were doing $(AS) -o /dev/null ...  in both
that test, as well as another.  The problem here is that the checkbin
target is run on the install targets, meaning that /dev/null will get
unlinked when the test passes.  To get around this we use .tmp_gas_check
as the output file instead.

NFS takes some thought to switch to the new symlink scheme, because we
can't rely on the pagecache lookup to find the symlink page when freeing
it - the cache might have been invalidated in the meantime. 

So we hide the page information in the symlink data area itself,
by stealing the last pointer in the page used for the cache. That
way nfs_put_link() can just look up the page directly.

Both gcc and sparse will speed up tokenization by noticing
when a header file is protected by the standard preprocessor
#ifndef .. #endif exclusion.

However, that requires that the headers actually _use_ that
standard exclusion. Some did their own little broken dance.
