   Tests to see if this driver supports a given controller. If a child device is provided,
   it further tests to see if this driver supports creating a handle for the specified child device.

   This function checks to see if the driver specified by This supports the device specified by
   ControllerHandle. Drivers will typically use the device path attached to
   ControllerHandle and/or the services from the bus I/O abstraction attached to
   ControllerHandle to determine if the driver supports ControllerHandle. This function
   may be called many times during platform initialization. In order to reduce boot times, the tests
   performed by this function must be very small, and take as little time as possible to execute. This
   function must not change the state of any hardware devices, and this function must be aware that the
   device specified by ControllerHandle may already be managed by the same driver or a
   different driver. This function must match its calls to AllocatePages() with FreePages(),
   AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
   Because ControllerHandle may have been previously started by the same driver, if a protocol is
   already in the opened state, then it must not be closed with CloseProtocol(). This is required

                                    an I/O abstraction to the driver.
   @param[in]  RemainingDevicePath  A pointer to the remaining portion of a device path.  This
                                    parameter is ignored by device drivers, and is optional for bus
                                    drivers. For bus drivers, if this parameter is not NULL, then
                                    the bus driver must determine if the bus controller specified
                                    by ControllerHandle and the child controller specified
                                    by RemainingDevicePath are both supported by this
                                    bus driver.

	Tests to see if this driver supports a given controller. If a child device is provided,
	it further tests to see if this driver supports creating a handle for the specified child device.

	This function checks to see if the driver specified by This supports the device specified by
	ControllerHandle. Drivers will typically use the device path attached to
	ControllerHandle and/or the services from the bus I/O abstraction attached to
	ControllerHandle to determine if the driver supports ControllerHandle. This function
	may be called many times during platform initialization. In order to reduce boot times, the tests
	performed by this function must be very small, and take as little time as possible to execute. This
	function must not change the state of any hardware devices, and this function must be aware that the
	device specified by ControllerHandle may already be managed by the same driver or a
	different driver. This function must match its calls to AllocatePages() with FreePages(),
	AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
	Because ControllerHandle may have been previously started by the same driver, if a protocol is
	already in the opened state, then it must not be closed with CloseProtocol(). This is required
	to guarantee the state of ControllerHandle is not modified by this function.

	@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
	@param[in] ControllerHandle The handle of the controller to test. This handle
	must support a protocol interface that supplies
	an I/O abstraction to the driver.
	@param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
	parameter is ignored by device drivers, and is optional for bus
	drivers. For bus drivers, if this parameter is not NULL, then
	the bus driver must determine if the bus controller specified
	by ControllerHandle and the child controller specified
	by RemainingDevicePath are both supported by this
	bus driver.
