The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC

This is a follow up to the previously submitted commit cefa9a31 (ehci-pci:
disable for Intel MID platforms).

It includes the following changes:
- table and function are renamed to reflect this is not only about ChipIdea
- ChipIdea PCI driver (ci_hdrc_pci.c) gets the comment about the table in
  ehci-pci.c
- MIPS IDs removed from the list since it was discovered and tested on Intel
  MID platforms

The usb_hcd_unlink_urb() routine in hcd.c contains two possible
use-after-free errors.  The dev_dbg() statement at the end of the
routine dereferences urb and urb->dev even though both structures may
have been deallocated.

This patch fixes the problem by storing urb->dev in a local variable
(avoiding the dereference of urb) and moving the dev_dbg() up before
the usb_put_dev() call.

Currently the USB stack assumes that all host controller drivers are
capable of receiving wakeup requests from downstream devices.
However, this isn't true for the isp1760-hcd driver, which means that
it isn't safe to do a runtime suspend of any device attached to a
root-hub port if the device requires wakeup.

This patch adds a "cant_recv_wakeups" flag to the usb_hcd structure
and sets the flag in isp1760-hcd.  The core is modified to prevent a
direct child of the root hub from being put into runtime suspend with
wakeup enabled if the flag is set.

The usbfs API has a peculiar hole: Users are not allowed to reap their
URBs after the device has been disconnected.  There doesn't seem to be
any good reason for this; it is an ad-hoc inconsistency.

The patch allows users to issue the USBDEVFS_REAPURB and
USBDEVFS_REAPURBNDELAY ioctls (together with their 32-bit counterparts
on 64-bit systems) even after the device is gone.  If no URBs are
pending for a disconnected device then the ioctls will return -ENODEV
rather than -EAGAIN, because obviously no new URBs will ever be able
to complete.

The patch also adds a new capability flag for
USBDEVFS_GET_CAPABILITIES to indicate that the reap-after-disconnect
feature is supported.

I recently posted a patch ("storage: Add quirk for another SCM-based
USB-SCSI converter") to add a quirk for the converter with ID 04E6:000F,
which is listed along with 04E6:000B in the Windows INF file for the
Startech ICUSBSCSI2 as "eUSB SCSI Adapter (Bus Powered)".

The already-present quirk for 04E6:000B has USB_SC_SCSI/USB_PR_BULK, not
USB_SC_DEVICE/USB_PR_DEVICE. Change the 04E6:000F quirk to match that,
since it will probably be required.

This device needs to be continuously clocked to provide wake up support,
previously, if STANDBY target were chosen the device were
enable_irq_wake()-prepared and clock still active and if MEM target were
chosen the device were also enable_irq_wake()-prepared but not clocked
anymore, which is wrong.

Now, if STANDBY target is chosen the device is still clocked with wake
up support enabled, which were the previous default and if MEM target is
chosen the device is declocked with wake up support disabled.
