* arch/arm/src/sama5/sam_ohci.c and sam_usbhost.h (was sam_ohci.h), and
configs/sama5d3x-ek/src/sam_usb.c, and sama5d3x-ek.h: Add controls
to enable VBUS power in OHCI host most (2013-8-12).
* includes/nuttx/usb/usbhost.h, all USB host drivers in arch/, and all
USB host-side connection monitoring threads in configs/*/src: The
SAMA5 has three downstream ports; all of the other USB host
implementations have only one. This will require significant changes
to the USB host interfaces starting with these chnages to monitor
connections on a port-by-port basis. This effects a lot of files and
more changes are coming for this issues. Changes are being blindly
incorporated into other architrectures. I am being careful to avoid
breakage, but I expect some (2013-8-12).

* Description:
* Wait for a device to be connected or disconneced.
* Wait for a device to be connected or disconnected to/from a root hub port.
*
* Input Parameters:
* drvr - The USB host driver instance obtained as a parameter from the call to
* the class create() method.
* connected - TRUE: Wait for device to be connected; FALSE: wait for device to
* be disconnected
* drvr - The USB host driver instance obtained as a parameter from the call
* to the class create() method.
* connected - A pointer to an array of n boolean values corresponding to
* root hubs 1 through n. For each boolean value: TRUE: Wait for a device
* to be connected on the root hub; FALSE: wait for device to be
* disconnected from the root hub.
*
* Returned Values:
* Zero (OK) is returned when a device in connected. This function will not
* return until either (1) a device is connected or (2) some failure occurs.
* On a failure, a negated errno value is returned indicating the nature of
* the failure
* And index [0..(n-1)} corresponding to the root hub port number {1..n} is
* returned when a device in connected or disconnectd. This function will not
* return until either (1) a device is connected or disconntect to/from any
* root hub port or until (2) some failure occurs. On a failure, a negated
* errno value is returned indicating the nature of the failure
*
* Assumptions:
* This function will *not* be called from an interrupt handler.
* - Called from a single thread so no mutual exclusion is required.
* - Never called from an interrupt handler.
