ENGR00161607 mxc v4l2 output: return real phys offset after mmap

vpu unit test failed because it need phys offset of each buffer allocated by
v4l2 output driver.
videobuf dma contig method only allocate real dma buffer when user call mmap.
Fix this issue by adding code to querybuf ioctl, return real phys after
buffer mmaped.
