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.

suspended ports to be taken out of suspend when the USBCMD.Run/Stop

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.

USB: fix interface runtime-PM settings
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.

USB: ohci: Add Kconfig entries for ohci-omap3
On OMAP systems, we have two different OHCI controllers. The legacy
one is present in OMAP1/2 chips, and the newer one comes bundled as
a companion to the EHCI controller on OMAP3 and newer chips.
We may have multi-omap configurations where OMAP2 and OMAP3
support may be enabled in the same kernel, and need a mechanism
to keep both drivers around.
This patch adds a Kconfig entry for each of these drivers.

USB: ohci: introduce omap3 ohci-hcd driver
Add support for the OHCI controller present in OMAP3 and newer chips.
The code is mostly based off the ehci-omap.c driver.
Some of it is common to both drivers and will eventually
need to be factored out to platform init files.
In its current state, the driver cannot co-exist with the ehci-omap
driver, and this will be fixed in later versions. The second driver
to be loaded will overwrite settings made by the other. For now,
this driver should allow the few users of OMAP3 OHCI to get going.

Reverse priority of errors reported to ldisc so that it matches that of
other serial drivers (break takes precedence over parity, which takes
precedence over framing errors).
Also make sure overrun errors are handled as in other drivers, that is,
an overrun error is always reported and is not associated with any
received character (instead a NULL character with the TTY_OVERRUN flag
set is inserted).
