broadcom/vc4: Mark BOs as purgeable when they enter the BO cache
This patch makes use of the DRM_IOCTL_VC4_GEM_MADVISE ioctl to mark all
BOs placed in the mesa BO cache as purgeable so that the system can
reclaim this memory under memory pressure.
v2:
- Removed BOs from the cache when they've been purged by the kernel
- Check whether the madvise ioctl is supported or not before using it
v3: Don't walk the whole list when we find a busy BO (by anholt, acked by
Boris)
