From: Somalapuram Amaranath <amaranath.somalapu...@amd.com>
Instead of a list of separate busy placement add flags which indicate
that a placement should only be used when there is room or if we need to
evict.
v2: add missing TTM_PL_FLAG_IDLE for i915
v3: fix auto build test ERROR on drm-tip/drm-tip
v4: fix some typos pointed out by checkpatch
v5: cleanup some rebase problems with VMWGFX
