drm/radeon/kms: Rework radeon object handling
The locking & protection of radeon object was somewhat messy. This patch completely rework it to now use ttm reserve as a protection for the radeon object structure member. It also shrink down the various radeon object structure by removing field which were redondant with the ttm information. Last it converts few simple functions to inline which should with performances. airlied: rebase on top of r600 and other changes.
