This patch adds support for an olivetti olicard100 HЅDPA usb-stick.

This device is a zeroCD one with ID 0b3c:c700 that needs switching via
eject or usb-modeswitch with
MessageContent="5553424312345678000000000000061b000000030000000000000000000000".
After switching it has ID 0b3c:c000 and provides 5 serial ports ttyUSB[0-4].
Port 0 (modem) and 4 are interrupt ports.

This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers.  When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.

In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops).  This requires extra code, but the total delay
time is reduced.

There are also a few additional minor cleanups.

In to places in fsg_common_init() an unconditional call to kfree()
on common was performed in error recovery which is not a valid
behaviour since fsg_common structure is not always allocated by
fsg_common_init().

To fix, the calls has been replaced with a goto to a proper error
recovery which does the correct thing.

Also, refactored fsg_common_release() function.

An undocumented "feature" in the OMAP3 EHCI controller causes
suspended ports to be taken out of suspend when the USBCMD.Run/Stop
bit is cleared (this bit is normally cleared when ehci_bus_suspend
is called).

This "feature" breaks suspend-resume if the root-hub is allowed
to suspend. (The controller thinks it is in resume, and the PHY
thinks it is still in suspend).

There is an undocumented register bit that can be used to disable
this feature and restore normal behavior. Set this bit so
suspend-resume can work normally.

Tested on OMAP3 SDPs with the NXP ISP1504 and NXP ISP1703 PHYs.

This patch (as1379) reworks the logic for handling USB interface
runtime-PM settings -- hopefully it's right this time!  The problem is
that when a driver is unbound or binding fails, runtime PM for the
interface always gets disabled.  But pm_runtime_disable() nests, so it
shouldn't be called unless the interface was previously enabled for
runtime PM.
