drm/tegra: Fixes for v3.15-rc2

Browse source 
This contains a fix for the host1x driver writing to non-existent syncpt
 registers.
 
 A second commit removes an excess pad field in the parameter structure
 for the DRM_TEGRA_SUBMIT IOCTL. Archeaology on earlier versions of this
 file indicates that this was once there to pad an uneven number of u32
 u32 fields, of which one was subsequently removed. Unfortunately nobody
 remembered to get rid of the padding when that happened.
 
 Both of these commits are Cc: stable because they fix issues that were
 introduced back in v3.10.
