drm/radeon/kms: simplify memory controller setup V2
Get rid of _location and use _start/_end also simplify the computation of vram_start|end & gtt_start|end. For R1XX-R2XX we place VRAM at the same address of PCI aperture, those GPU shouldn't have much memory and seems to behave better when setup that way. For R3XX and newer we place VRAM at 0. For R6XX-R7XX AGP we place VRAM before or after AGP aperture this might limit to limit the VRAM size but it's very unlikely. For IGP we don't change the VRAM placement. Tested on (compiz,quake3,suspend/resume): PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710 AGP:RV100,RV280,R420,RV350,RV620(RPB*),RV730 IGP:RS480(RPB*),RS690,RS780(RPB*),RS880 RPB: resume previously broken V2 correct commit message to reflect more accurately the bug and move VRAM placement to 0 for most of the GPU to avoid limiting VRAM.
