drm/radeon/kms: Rework radeon object handling

Browse Source 
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.
