Update DT bindings for mdp. We now have a more uniform and future-proof
set of compatible strings.

MDP5 bindings were missing. Add those and update details on the
clock-names properties.

Create distinct compatible strings for mdp4 and mdp5. Keep "qcom,mdss_mdp"
as is to support downstream kernels.

Support for non-DT kernels was mainly to use v3.4 downstream kernels.
This is no longer a priority now as we have reasonable support upstream.

Remove CONFIG_OF from the top level msm_drv.c file. While we're at it,
clean up the data matching process using of_device_get_match_data.

MDP5 has line count and frame count registers for each interface. Enable
these counters and use them to implement the get_vblank_timestamp drm
driver op.

The line counter starts with the value 1 at the beginning of the VSYNC
pulse and ends with value VTOTAL at the end of VFP. This value is used
to determine whether we're in blanking period or not, and an adjusted
value of this counter is used to get vpos as expected by
get_scanout_position. Since there is no way to calculate hpos, we always
set it to 0.

Fix all the problems with the header files and userspace builds

libdrm imports.

New -misc pull. Big thing is Thierry's atomic helpers for system suspend

The ioctl IOC_LIBCFS_PING_TEST has not been used in ages.  The recent
nidstring changes which moved all the nidstring operations from libcfs
to the LNet layer but this ioctl code was still using an nidstring
operation that was causing a circular dependency loop between libcfs and
LNet.

 "A couple of fixes (-stable fodder) + dead code removal after the

  I agree that it's better to separate from the fix part to make

  removal until the next window"
