fsl_udc_core: Fix USB chapter9 compliance tests.
In udc driver ch9getstatus() function is not mapping the status buffer's
virtual address to hardware for transfering the status data over dma.
On USB bus get status information is not going properly to the host.
Hence, few chapter9 tests are failing. Fixed this by maping the status
buffer address to the dmable address. With this fix USB chapter9
(usb command verifier) tests are passing.
Bug 633510: Chapter 9 USB Compliance tests are failed.
Tested on whistler/android/usb1 port in device mode.
