usb: patches for v3.17 merge window

Surprisingly enough, while a big set of patches, the majority is
composed of cleanups (using devm_*, fixing sparse errors, moving
code around, adding const, etc).

The highlights are addition of new support for PLX USB338x devices,
and support for USB 2.0-only configurations of the DWC3 IP core.

3e346d41bf USB: PHY: tegra: Call tegra_usb_phy_close only on device removal
tegra_usb_phy_close() is supposed to undo the effects of
tegra_usb_phy_init(). It is also currently added as the USB PHY shutdown
callback, which is wrong, since tegra_usb_phy_init() is only called
during probing wheras the shutdown callback can get called multiple
times. This then leads to warnings about unbalanced regulator_disable if
the EHCI driver is unbound and bound again at runtime.

508ccea177 usb: phy: msm: Do not do runtime pm if the phy is not idle
Use case is when the phy is configured in host mode and a usb device is
attached to board before bootup. On bootup, with the existing code and
runtime pm enabled, the driver would decrement the pm usage count
without checking the current state of the phy. This pm usage count
decrement would trigger the runtime pm which than would abort the
usb enumeration which was in progress. In my case a usb stick gets
detected and then immediatly the driver goes to low power mode which is
not correct.

freed in the remove function. The corresponding free functions are
removed and the labels are done away with.

Pull USB driver updates from Greg KH:
 "Here is the big USB driver pull request for 3.16-rc1.

  Nothing huge here, but lots of little things in the USB core, and in
  lots of drivers.  Hopefully the USB power management will be work
  better now that it has been reworked to do per-port power control
  dynamically.  There's also a raft of gadget driver updates and fixes,
  CONFIG_USB_DEBUG is finally gone now that everything has been
  converted over to the dynamic debug inteface, the last hold-out
  drivers were cleaned up and the config option removed.  There were
  also other minor things all through the drivers/usb/ tree, the
  shortlog shows this pretty well.

  All have been in linux-next, including the very last patch, which came
  from linux-next to fix a build issue on some platforms"

Pull ARM SoC board support updates from Olof Johansson:
 "The bulk of this branch is updates for Renesas Shmobile.  They are
  still doing some enablement for classic boards first, and then come up
  with DT bindings when they've had a chance to learn more about the
  hardware.  Not necessarily a bad way to go about it, and they're
  looking at moving some of the temporary board code resulting from it
  to drivers/staging instead to avoid the churn here.

  As a result of the shmobile clock cleanups, we end up merging quite a
  bit of SH code here as well.  We ended up merging it here instead of
  in the cleanup branch due to the other board changes depending on it"

usb: patches for v3.16 merge window

Not a lot here during this merge window. Mostly we just have
the usual miscellaneous patches (removal of unnecessary prints,
proper dependencies being added to Kconfig, build warning fixes,
new device ID, etc.

Other than those, the only important new features are the
new support for OS Strings which should help Linux Gadget
Drivers behave better under MS Windows. Also Babble Recovery
implementation for MUSB on AM335x. Lastly, we also have
ARCH_QCOM PHY support though phy-msm.

77c2f02edb ARM: OMAP: replace checks for CONFIG_USB_GADGET_OMAP
Commit 193ab2a607 ("usb: gadget: allow multiple gadgets to be built")
apparently required that checks for CONFIG_USB_GADGET_OMAP would be
replaced with checks for CONFIG_USB_OMAP. Do so now for the remaining
checks for CONFIG_USB_GADGET_OMAP, even though these checks have
basically been broken since v3.1.

And, since we're touching this code, use the IS_ENABLED() macro, so
things will now (hopefully) also work if USB_OMAP is modular.

2) We should request the memory before we remap it, and
   devm_ioremap_resource() does that.

c5ab571f81 usb: phy: msm: reset controller is mandatory now
Commit a273454341 "usb: phy: msm: Use reset framework for LINK
and PHY resets" introduced a mandatory call to reset_control_get
into the msm usb phy driver, which means we have to add a Kconfig
dependency on the API to avoid this build error:

phy/phy-msm-usb.c: In function 'msm_otg_read_dt':
phy/phy-msm-usb.c:1461:2: error: implicit declaration of function 'devm_reset_control_get' [-Werror=implicit-function-declaration]
  motg->link_rst = devm_reset_control_get(&pdev->dev, "link");
  ^

Since the usb-ehci-msm driver currently selects the OTG driver,
we could still get a broken dependency here. To solve that,
this patch also removes the 'select', which turns out to be
unnecessary.
