   Notes
   Both of these reset types are software based resets; and are
   distinct from a chip level HARD reset that is applied through
   the reset pin on the West Bridge.

   The CyAsResetSoft type resets only the on-chip micro-controller
   in the West Bridge. In this case, the previously loaded firmware
   will continue running. However, the Storage and USB stack
   operations will need to be restarted, as any state relating to
   these would have been lost.

/* Summary

   This function places West Bridge into a low power (sleep) mode, and

   placed into sleep mode.  This allows West Bridge to complete any pending
   storage operations.  After the West Bridge device has responded that
   pending operations are complete, the device is placed in standby mode.

   There are two methods of placing the device in standby mode.  If the
   WAKEUP pin of the West Bridge is connected to a GPIO on the processor,
   the pin is de-asserted (via the HAL layer) and West Bridge enters into
   a sleep mode.  If the WAKEUP pin is not accessible, the processor can
   write into the power management control/status register on the West
   Bridge to put the device into sleep mode.

/* Summary
   This function updates the state of a GPIO pin on the West
   Bridge device.

   Description
   The West Bridge device has GPIO pins that can be used for
   user defined functions. This function updates the output
   value driven on a specified GPIO pin. Calling this function
   will configure the corresponding pin as an output.

   * Valid In Asynchronous Callback: NO

   Notes
   All of the pins listed under CyAsMiscGpio can be used as GP
   outputs. This feature is note supported by firmware images
   that include NAND storage device support.

   Returns
   * CY_AS_ERROR_SUCCESS - the function completed successfully
   * CY_AS_ERROR_INVALID_HANDLE
   * CY_AS_ERROR_NOT_CONFIGURED - the West Bridge device has not
   *    been configured yet

/* Summary
   Set the West Bridge device in the low power suspend mode.

   Description
   The West Bridge device has a low power suspend mode where the USB
   core and the internal microcontroller are powered down. This
   function sets the West Bridge device into this low power mode.
   This mode can only be entered when there is no active USB
   connection; i.e., when USB has not been connected or is suspended;
   and there are no pending USB or storage asynchronous calls. The
   device will exit the suspend mode and resume handling USB and
   processor requests when any activity is detected on the CE#, D+/D-
   or GPIO[0] lines.

   * Valid In Asynchronous Callback: NO

   Notes
   The GPIO[0] pin needs to be configured as an input for the gpio
   wakeup to work. This flag should not be enabled if the pin is
   being used as a GP output.

   Returns
   * CY_AS_ERROR_SUCCESS - the device was placed in suspend mode.
   * CY_AS_ERROR_INVALID_HANDLE - the West Bridge handle passed
   *    in is invalid.
   * CY_AS_ERROR_NOT_CONFIGURED - the West Bridge device has not
   *    yet been configured.
   * CY_AS_ERROR_NO_FIRMWARE - no firmware has been downloaded

   * CY_AS_ERROR_IN_STANDBY - the device is already in sleep mode.

   * CY_AS_ERROR_OUT_OF_MEMORY - failed to allocate memory for

   A CyAsEventMiscWakeup event will be delivered to the callback
   registered with CyAsMiscRegisterCallback to indicate that the
