d1d3b883df host1x_emu: Fix NvHost Interface and IOCTL 
1. The nvhost interface like syncpoint offset/aperture were
taking "pdev" of Host1x device, but emulated syncpoint driver
implementd the interface with "pdev" of clinet device. This was
done to align all other interface input parameter.

This patch revert the above alignment of intput parameter change.

2. This patch modify SyncpointWait IOCTL handler to return timestamp
of signal observed by KMD to UMD
