USB: host: Atmel OHCI and EHCI drivers improvements

Suspend/resume support for EHCI.
struct dev_pm_ops for OHCI.
Removed global variables from both.
Fixed OHCI wake up support for STANDBY(wake-up enabled) and MEM(wake-up
disabled) sleep targets.

Changes since v6:
  * Collected Acked-by tags

Changes since v5:
  * Don't overwrite device wakeup flag with device_init_wakeup(),
    now using a private wakeup bool instead.

Changes since v4:
  * Re-add at91_suspend_entering_slow_clock() to OHCI, we can't naively
    remove this one, this device needs to be continuously clocked to
    provide wake up support.
    The removal of at91_suspend_entering_slow_clock() actually lighted up
    an issue on wake up support, which is now fixed.

Changes since v3:
  * Using struct dev_pm_ops instead of static struct platform_driver
    resume and suspend bindings for both EHCI and OHCI
  * Fixed inconsistency in patch subjects, _ intead of - for file names
  * Patch cleaning with the help of checkpatch.pl, fixed lines over
    80 characters

Changes since v2:
  * Added patchs from an other submission, because this series
    depended on this one
    * EHCI: Move global variables to private struct
    * OHCI: Move global variables to private struct
  * Using ohci->priv and ehci->priv instead of hcd->hcd_priv,
    which were not the right way to do that

Changes since v1:
  * Don't use at91_suspend_entering_slow_clock() on EHCI,
    we are trying to get read of this of this function
  * Removed at91_suspend_entering_slow_clock() from OHCI
