idx can be indirectly controlled by user-space, hence leading to a

This issue was detected with the help of Smatch:
drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c:408 amdgpu_set_pp_force_state()
warn: potential spectre issue 'data.states'
Fix this by sanitizing idx before using it to index data.states
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

Pull more drm updates from Dave Airlie:
"Fixes/cleanups for rc1, non-desktop flags for VR
- remove the MSM dt-bindings file Rob managed to push in the previous
pull.
- add a property/edid quirk to denote HMD devices, I had these
hanging around for a few weeks and Keith had done some work on
them, they are fairly self contained and small, and only affect
people using HTC Vive VR headsets so far.
- amdgpu, tegra, tilcdc, fsl fixes
- some imx-drm cleanups I missed, these seemed pretty small, and no
reason to hold off.
I have one TTM regression fix (fixes bochs-vga in qemu) sitting
