Minor updates to "Gadget Zero".
- Primarily these are whitespace updates to address the fact that since
this was written, Documentation/CodingStyle was changed to disapprove
of parts of the original coding style.
- Update a few comments that weren't quite correct, notably mentioning
the "autoresume" module parameter.

Based on a patch from <Aurel.Thomi@ruag.com>, this makes the
CDC-ACM support in the serial gadget handle the SET_LINE_CODING
and SET_CONTROL_LINE_STATE requests ... which should improve
interop with at least MS-Windows "usbser.sys" if not some other
ACM host drivers.
It also adds a few REVISIT comments where this code plays a bit
loose with the CDC ACM spec. If this were used to hook up to a
real RS232 or modem link, those places would need a bit of work.

Adds pxa27x udc driver to support USB peripherals on pxa27x chips.
The driver is compatible with: Gadget Zero, the File Storage
gadget, and the Ethernet gadget (only in CDC subset mode).
The driver can't properly support multiple interfaces, because
of hardware bugs without possible workaround. That means no
RNDIS support from g_ether, and no CDC ACM support in g_serial.

Minor cleanup to the "usbtest" driver, mostly to resolve a regression:
all the important diagnostics were at KERN_DEBUG, so that when the
"#define DEBUG" was removed from the top of that file it stopped
providing diagnostics. Fix by using KERN_ERROR. Also:
- Stop using the legacy dbg() calls
- Simplify the internal debug macros
- Correct some test descriptions:
* Test #10 subcase 7 should *always* stall
* Test #10 subcase 8 *may* stall
- Diagnostic about control queue test failures is more informative
- Fix some whitespace "bugs"
And add a warning about the rude interaction between usbfs ioctl()
and khubd during device disconnect ... don't unplug a device under
test, that will wedge.

The wodim says:
"close track/session scsi sendcmd: cmd timeout after 5.000 (480) s"
This happened because we ignored the supplied timeout and used 5s.
It's not completely correct to apply a timeout meant for the complete
command to any single URB, but we don't have many URBs per command, so
this is simple and works.

The return from software signal handling pushes code on the stack
that system calls to the kernels cleanup code. This is borrowed
directly from the m68k linux signal handler.
The rt signal case is not quite right for the restricted instruction
set of the ColdFire parts. And neither the normal signal case or rt
signal case properly flushes/pushes the appropriate cache lines.
Rework the return path to just call back through some code fragments
in the kernel proper (with no MMU in the way we can do this). No
cache problems, and less code overall.
