Revert "i915: Add GBM_BO_USE_HW_VIDEO_DECODER use flag"

This reverts commit 1bd7b04a3ae68c0314bdee06c559093de9e5a304.

Reason for revert: Breaks video decoding on most intel platforms, e.g., caroline and samus

Original change's description:
> i915: Add GBM_BO_USE_HW_VIDEO_DECODER use flag
> 
> This flag is used to indicate that the platform video decoder will be
> writing into this buffer and that it should be allocated
> accordingly. On Intel, this means that we have to allocate y-tiled
> NV12 for libva to be able to decode to the buffer.
> 
> We force gralloc NV12 allocations to be linear for now, since ARC++
> doesn't properly pass modifiers to ChromeOS.
> 
> BUG=822346
